Trek Stache 5 review

An unconventional 29er for the trails

Russell Burton

Guy Kesteven

Amazing small bump, rough surface rolling speed and crazy traction from the rubber dinghy sized tyres. Surprisingly agile handling and no suspension set-up, maintenance or extra weight to worry about

Expensive frame, rolling stock and carbon fork mean average, not advantageous, components. Once bigger blows start it bouncing it’s hard to stop and it’s as pressure sensitive and as likely to puncture as other plus bikes

When it came to supplying a bike for testing, the Trek demo cupboard was almost bare apart from the uniquely freaky Stache 5. We’d heard consistently great things about this monster wheel machine all year though, so we were keen to find out if this radical head turner was a genuine opinion changer on the trail.

• Trek Stache 9 - long-term review
• Highlights from the 2017 Trek mountain bike range
• Best 29er trail bikes

It’s immediately obvious that the Stache 5 is far from conventional, even in today’s broad reaching MTB landscape. 3in wide Bontrager Chupacabra 29er plus tyres sit on windowed, 50mm wide Mulefüt rims. The result is a similar ground smoothing low pressure footprint to a 27.5in plus-tyre, but amplified in terms of bump shrinking speed sustained by the shallower contact angle of the 29in diameter.

Trek has managed to keep the Stache 5 feeling genuinely agile in terms of steering

Once you’ve got these rubber dinghies rotating, the smoothing effect on rolling, rocky or rooty trails is genuinely amazing. You’ll only miss not having any suspension when you start hitting bigger blocks and drops and the tyres start bottoming out and bouncing. As long as you get the tyre pressure right they’ve got the same traction levels as a slug on a wet window too.

By using a radical curved tube, asymmetric raised chainstay frame, Trek has managed to keep the Stache 5 feeling genuinely agile in terms of steering. The carbon rigid fork keeps weight down to an effervescent 12.18kg that’s easy to pop and hop over potential trouble and amplifies its feeling of float even further.

With the frame-only option costing £700, single ring component spec is okay rather than outstanding. It’s equally tyre pressure dependent and potentially puncture prone as other plus rides too, although the ‘Stranglehold’ dropouts make it compatible with conventional 29er or 27.5in plus wheels too.

Trek Stache 5

With Stache 5, you don't have to pay a big cover charge to get into the 29+ party. It's a trail hardtail that rolls on 3-inch mid-fat tires for monster-truck traction on rough and loose terrain. This mountain bike is equipped with a burly suspension fork to keep you on your line when things get rowdy and a frame that delivers a lively and fun ride with its astonishingly short chainstays. It's right for you if... You ride because riding is fun, and you don't want to fuss with a full-suspension rig. You prioritize solid, dependable parts over the latest high-priced gadget, and want a bike you can take anywhere, from gravel bikepacking adventures to marathon singletrack days to gnarly, rocky routes. The tech you get An Alpha Platinum Aluminum frame with innovative features like an elevated midstay, Stranglehold dropouts, and Boost hub spacing for tons of tire clearance. The wide 3-inch tires mounted to 50mm SUNringle rims deliver unbelievable traction, but are still spry enough to pop off jumps and scramble up climbs. Plus, it has a Shimano Deore 1x10 drivetrain with hydraulic disc brakes, a Manitou Machete 32 Comp fork with 120mm of travel, and a dropper post. The final word Stache 5 is an absolute blast. The short chainstays deliver a lively ride and quick acceleration, while the mid-fat tires grip loose terrain relentlessly and steamroll over obstacles. It's built with solid components that will hold up for all the good times on the trail. Why you'll love it 1 - Stache is super versatile and equally at home on multi-day bikepacking trips as it is on rough singletrack 2 - The super-short chainstays make it really easy to show off your wheelie skills 3 - This model gives you most of the performance of the higher-end models for way less money 4 - Traction satisfaction: the mid-fat tires immediately make you a more confident and capable rider 5 - We're not the only ones who love it: DirtRag says, "[Stache] is the most fun bike I rode this year, and fun is where it's at."

Understanding Trek's naming system

Trek's naming system follows a similar style to how Canyon names its bikes. Each bike's name is suffixed with a number, with higher value numbers corresponding to pricier and better-kitted bikes. Once we get to 9, Trek adds decimals to the suffix to denote changes in the bike's suspension package. All bikes with a 9 in the name get carbon frames but a 9.7 might get its suspension from Fox's Rhythm range for example, while a 9.8 will get better something from higher in the range. Also, you'll see that a lot of kit on the bikes come from Bontrager, for the uninitiated that's Trek's in-house component brand.

At the '9' level, we also see XT, XO1, and GX finding their way into the names. Yep, you've guessed it, that's the drivetrain the bike comes kitted with.

Another thing that's definitely worth mentioning is that a small selection of Trek's bike range is available through what the brand calls Project One. Project One offers the opportunity to have your bike personalised and custom painted with special, exclusive colours. This will mean you have to part ways with a heap of cash but in return, you'll get a bike that's unique to you.

As with the brand's range of bikes, the price range is vast with bikes starting from £440, right up to £9,200 and that's not even considering the Project One options. There's also a comprehensive range of gravel bikes and e-bikes.

Let's kick things off with the Slash. It's Trek's enduro bike which rolls on 29" wheels and gets 160mm of travel at the rear, paired with 170mm at the front. For 2021 it gets both an aluminium and carbon frame option all of which benefit from Trek's proprietary Knock Block system which saves your top and down tube if your front end spins during a crash. This bike also gets the Mino Link which is a geometry adjusting flip-chip, down tube guards threaded bottom brackets, an Active Braking Pivot, and storage in the downtube. As for the geometry, in the low setting, the Slash sees a 75.6° effective seat tube angle, a 64.1° head tube angle, and a 435mm chainstay. A large frame gets a 486mm reach. If you're after something a little more special, the Slash is available through Project One.

Slash 9.9 XTR

Topping the Slash range is the Slash 9.9 XTR. It gets Trek's OCLV carbon frame with the all-new RockShox Super Deluxe Ultimate shock with an updated ThruShaft damper. At the front, you'll find the RockShox ZEB Ultimate RC2 which features chunky 38mm stanchions. As its name suggests there's a full Shimano XTR 12-speed drivetrain with an e*thirteen LG1 Race Carbon crank. The brakes here also come from the XTR lineup and they come with 4-pot calipers for extra stopping power. This bike rolls on a pair of Bontrager Line Pro 30 which are wrapped with a Bontrager SE5 Team Issue 2.6" Tubeless Ready, Core Strength sidewall, aramid bead tyre at the front and an SE5 Team Issue with the same spec in 2.4" at the rear. It also gets a Bontrager Line Elite Dropper with Bontrager supplying the 820mm wide carbon bar, 35mm stem along with the rest of the build kit.

Slash 9.9 XO1

The Slash 9.9 XO1 gets all of the same trimmings as the 9.9 XTR but benefits from a SRAM XO1 Eagle drivetrain and SRAM Code RSC Brakes, along with a slightly friendlier price tag.

Slash 9.8 GX

Shaving a few thousand pounds of the range-topper is the 9.8 GX. This one is still built around Trek's carbon frame but this one gets a slightly downgraded RockShox ZEB Select+ RC with a RockShox Super Deluxe Ultimate. Here we get a SRAM GX drivetrain with a matching crankset and SRAM Code R brakes. As for the rest of the bike, it's the same as the 9.9 XTR.

Slash 9.8 XT

As its name suggests, the Slash 9.8 XT gets a very similar built kit to the 9.8 GX. However, this bike sees a Shimano XT drivetrain with SLX M7120 four-piston brakes.

Dropping a full £1.8k off of the 9.8 models, the Slash 9.7 is still built around a carbon frame and it swaps the RockShox suspension with a Fox Rhythm 36 fork and a Fox Performance DPX2 EVOL shock. The drivetrain is a mix of SRAM GX and NX Eagle and the wheels here are the alloy Bontrager Line Comp 30's. Those come shod with a Bontrager XR5 Team Issue, Tubeless Ready, Inner Strength sidewall, aramid bead 2.6" tyre at the front with a Bontrager XR4 with the same spec and a 2.4" width at the rear. Trek has also swapped the dropper post for a TransX post and there's Bontrager's own alloy finishing kit.

With the Slash 8, we no longer get a carbon frame but we do get a RockShox Lyric Select+ RC fork with a RockShox Super Deluxe Ultimate at the rear. This bike is driven by a SRAM GX Eagle drivetrain and there's a pair of SRAM Code R brakes. Everything else is the same as what you would get on the 9.7 model.

The Slash 7 rounds of the range with its alloy frame, RockShox Yari RC fork, RockShox Deluxe Select+ shock, and SRAM NX drivetrain. Here we get a pair of SRAM Guide T brakes and the rest of the bike follows suit with the 8.

Trek Remedy

The Remedy is Trek's long-legged trail bike which comes with four models for 2021. It rolls on 650b wheels and gets 160mm of travel at the front, with 150mm at the rear. Much like the Slash, the Remedy benefits from the Knock Block, the Active Braking Pivot, and the Mino Link. Geometry-wise, it gets a 65.6° head angle, a 74.2° effective seat tube angle, and 435mm chainstays in the low position. A large frame gets a 455mm reach, again in that low setting.

The Remedy 9.8 is the only bike in the 2021 line up that gets a carbon frame. It also gets a burly Fox Performance 38 paired with a Fox Performance Float DPX2 EVOL shock at the rear. This bike benefits from a SRAM GX Eagle drivetrain matched with SRAM Code R brakes. As for the wheels, they're a pair of carbon Bontrager Line Elite 30's and they're wrapped with a Bontrager SE5 Team Issue, Tubeless Ready, Core Strength sidewalls with an aramid bead in 2.6" with a Bontrager SE4 Team Issue with the same specs in the 2.4" width. Bontrager also supplies the dropper post with the Line Elite and the 820mm handlebar along with the 35mm stem.

As suggested by the lack of a '9' in its name, the Slash 8 comes kitted with an alloy frame. As for the fork, it's a RockShox Lyrik Select+ RC and that's paired with a RockShox Super Deluxe Select+ shock. This bike is also driven by a SRAM GX Eagle drivetrain and it gets the same brakes as the 9.8 rig. Differing from the range-topper, this build sees in a pair of Bontrager Line Comp 30 alloy wheels which get an XR5 Team Issue tyre that's tubeless-ready with Inner Strength sidewalls and an aramid bead in 2.6", also from Bontrager. At the rear, there's an XR4 with the very same specification. The rest of the bike follows suit with the 9.8 model.

Remedy 8 XT

Rather unsurprisingly, the Remedy 8 XT comes with a very similar build to the 8 but gets an XT drivetrain and Deore M6120 four-pot brakes. Everything else on this build matches the Remedy 8.

The Remedy 7 is the cheapest 2021 Remedy on offer. It gets a RockShox Gold RL fork and a RockShox Deluxe Select+ shock. There's a SRAM NX drivetrain with SRAM Guide T brakes. Apart from that, everything else is the same as what you'll get on the Remedy 8's.

Trek Fuel EX

The Fuel EX is Trek's do it all trail bike. It gets 130mm of rear travel and 140mm at the front. Just like the Slash, the Fuel EX gets built-in downtube storage and the Active Braking Pivot. It comes with a RE:aktiv shock with Thru Shaft, something that you'll only find on Trek bikes. It promises more grip and control with a shock the reacts to the ground faster than anything else on the market, says Trek. This bike also gets the Mino Link, Knock Block, and Straight Shot downtube. The Fuel EX comes in five sizes with XS getting 650b hoops and M upwards getting 29" wheels. However, size S comes with a choice of either wheel size. As for the geometry in the low setting, the bike gets a 66° head angle, a 75° effective seat tube angle, and a 437mm chain stay. A large frame benefits from a 470mm reach.

Fuel EX 9.9 AXS

Topping the range with a pretty hefty pricetag is the 9.9 AXS. On this model, you'll get a Fox Factory 36 with a GRIP 2 damper, paired with a Fox Factory Float EVOL RE:aktiv shock. Of course, we then get wireless shifting from SRAM and the AXS range along with a wireless RockShox Reverb AXS dropper. It rolls on a pair of Bontrager Line 30 carbon wheels and they're wrapped with two Bontrager XR4 Team Issue tyres with Inner Strength sidewalls and aramid beads, measuring in with a 2.6" width at the front and a 2.4" at the rear. Bontrager supplies the finishing kit with a Knock Block stem and a 780mm OCLV carbon handlebar.

Fuel EX 9.9 XTR & XO1

Next up, the Fuel EX 9.9 XTR gets all of the bling. It's built around Trek's OCLV carbon frame and gets a Fox Factory 36 fork with a GRIP2 damper. At the back, there's a Fox Factory Float EVOL, RE:aktiv. As its name hints, this bike comes with a Shimano XTR 12-speed drivetrain with matching XTR M9120 four-piston brakes. There's also an option with a SRAM XO1 drivetrain with SRAM G2 RSC brakes. This one rolls on a pair of Bontrager Line Pro 30 OCLV carbon wheels which are wrapped in a pair of Bontrager XR4 Team Issue, Tubeless Ready tyres with the brand's Inner Strength sidewalls and aramid bead. At the front, there's a 2.6" tyre with a 2.4" at the rear on both wheel sizes. Then the bike comes kitted with a Bontrager Line Elite Dropper and the rest of the kit comes from the same brand.

Fuel EX 9.8 XT & GX

Offering a saving of over £2,000 over the top of the range bike is the 9.8 GX and XT. This bike comes with the same carbon frame as the most expensive bike but sees a downgrade in suspension and drivetrain. Here we get a Fox Performance 36 with a GRIP damper and a Fox Performance Float EVOL, RE:aktiv shock. This rig comes with a choice of drivetrain with either SRAM's GX groupset or Shimano's XT. The GX build comes with SRAM G2 RS brakes whereas the XT model is stopped with a pair of Shimano SLX M7120 four-piston brakes. Everything else on these builds is the same as what you'll find on the 9.9 XTR model.

Fuel EX 9.7

The 9.7 is Trek's most affordable carbon-framed Fuel EX. It comes kitted with a Fox Rhythm 36 with a GRIP damper and a Fox Performance Float EVOL shock. The drivetrain here is a mix of SRAM NX and GX with the former making up the shifter and the latter handing the mech. Gone are the carbon wheels, unfortunately, but instead we get a set of Bontrager Line Comp 30 wheels wrapped in the very same tyres like the rest of the range. The rest of the bike follows suit with the pricier models but there's an alloy bar and stem.

Fuel EX 8 XT & GX

At the sub £3k mark Trek does away with the carbon frames and replaces them with cheaper alloy alternatives. On the priciest alloy option, we get a Fox Rythm 34 Float with a GRIP damper and a Fox Performance Float EVOL RE:aktiv shock. On this build, there's a choice of either a SRAM GX Eagle drivetrain or a Shimano XT with the former benefitting from SRAM G2 R brakes and the latter receiving a pair of Shimano MT4100 levers mated to MT420 four-piston callipers. This bike gets a pair of Bontrager Line Comp 30 alloy wheels and the rest of the build is the same as what you'll get on the 9.7 bike.

Fuel EX 7 NX

On the Fuel EX 7 NX we find a RockShox 35 Gold RL fork and a Fox Performance Float EVOL shock, note that this shock doesn't come with that special RE:aktiv tech. You've guessed it, this one comes equipped with a SRAM NX Eagle drivetrain it gets its brakes from Shimano with a pair of MT4100 levers and MT410 callipers. The rest of the bike, including the wheels and tyres on this bike, is the same as the rest of the alloy range but we see a TransX dropper on this model.

Fuel EX 5 Deore

Rounding off the fairly extensive range is the reasonably priced Fuel EX Deore. It gets a RockShox Recon Silver fork with an X-Fusion Pro 2 shock. Then there's the Shimano Deore 12-speed drivetrain with Shimano brakes made up of MT201 levers and MT200 callipers. The wheels see a downgrade from the rest of the range with an Alex MD35 rim laced to Bontrager hubs. They're wrapped in a pair of Bontrager XR4 tyres and there's a TransX dropper post. The rest of the finishing kit comes from Bontrager.

Trek Top Fuel

Like it or not, but down-country bikes are becoming more and more prolific. Luckily for those who are on board with the trend Trek has a bike for you. It comes kitted with 120mm travel up front and 115mm at the rear with 29" wheels. In keeping with the rest of Trek's bikes so far the Top Fuel also gets a Straight Shot downtube and Trek's Active Braking Pivot. It's also kitted with the Mino Link and Control Freak cable management system. Moving onto the geometry, the Top Fuel sees a 68° head tube angle, a 75.7° effective seat tube angle and a 434mm chainstay. A large frame gets a 470mm reach and those numbers have been taken with the bike in its low setting. As for frame sizes, there's a choice from XS right up to XXL.

Top Fuel 9.9 XX1 AXS

A few hundred pounds shy of the 10k mark, this bike comes with all of the top tech. It's made around a carbon frame with a RockShox SID Ultimate fork with a Race Day Charger damper and a RockShox SID Luxe Ultimate shock. There's a RockShox TwistLoc Full Sprint lockout remote too. As for the drivetrain, here we get a SRAM XX1 Eagle AXS 12-speed wireless set up with SRAM G2 Ultimate brakes. The wheels on this bike area pair of Bontrager Kovee Pro 30 Carbon hoops and they're kitted with a pair of Bontrager XR3 Team Issue, Tubeless Ready tyres with Inner Strength sidewalls and aramid beads in a 2.4" width. Finally, there's a RockShox Reverb AXS wireless dropper post, Bontrager OCLV carbon bar with a 750mm width and 35mm clamp and a Bontrager stem.

Top Fuel 9.9 XTR & XO1

Next up, the Top Fuel XTR and XO1 models get the same carbon frame but this time there's a Fox Factory 34 Step Cast with a FIT4 damper paired with a Fox Factory Float shock. This bike also gets the RockShox Twistloc remote lockout. With this model, there's a choice of either a SRAM XO1 drivetrain or the Shimano XTR set up. The XO1 model gets SRAM G2 RSC four-piston brakes while the XTR gets XTR M9100 brakes. Everything else on the bike is the same as the AXS model but the dropper, which is a Bontrager Line Elite.

Top Fuel 9.8 XT & GX

The Top Fuel 9.8 sees a saving of £2.4k and gets its suspension from RockShox with the SID Select+ RL fork and RockShox SID Ultimate RL shock. There's a choice of drivetrain on this bike too between either a SRAM GX Eagle 12-speed with SRAM G2 RSC brakes or a Shimano XT drivetrain with SLX M7000 brakes. Everything else on this bike is the same as its pricier brethren.

Top Fuel 9.7

The 9.7 model is the cheapest with a carbon frame and it comes with a RockShox Reba RL fork and a Fox Performance Float DPS shock. There's a SRAM NX Eagle 12-speed drivetrain with Shimano brakes consisting of MT501 levers and MT500 calipers. This bike makes a move to Bontrager Kovee Comp 23 alloy wheels and they get the same tyres as the rest of the range. We get an alloy cockpit and a Bontrager Line Dropper.

Top Fuel 8 NX

At this price point, Trek introduces alloy frames into the mix. With the 8 NX there's a RockShox Recon Gold RL Solo Air with a Fox Performance Float DPS. There's still a remote lockout here but it comes from Bontrager in the form of the Drop Lock. As its name suggests, this bike is driven by a SRAM NX drivetrain and it's stopped with a pair of SRAM Level T brakes. The rest of the bike is the same as what you'll find on the 9.7 model.

Top Fuel 7 SX

The Top Fuel 7 SX is the most affordable bike in the range featuring suspension from RockShox with the Judy SL Solo Air fork and the X-Fusion Pro 2 shock. There's a SRAM SX Eagle 12-speed drivetrain with Shimano MT200 brakes. This one rolls on the same alloy wheels as the rest of the range with the same tyres. In fact, apart from the TransX dropper post, everything else matches the Top Fuel 8 NX.

Trek Full Stache

While the Full Stache hasn't had an update for 2021, it seems rude not to include it as there aren't an awful lot of full suspension 29+ bikes on the market. Of course, it rolls on 29" wheels with chunky 3" tyres. It also has 130mm of travel at both ends but the frame is compatible with up to a 140mm fork if you fancy some extra lairy riding. There's also the Mino Link, Control Freak cable management and the Knock Block. It's built around an aluminium frame and gets a 67° head tube angle, a 75.5° effective seat tube and a 430mm chainstay in the low setting. A large gets a 480mm reach, again in the low setting.

Full Stache 8

With its aluminium frame, you'll find a RockShox Pike Select Plus RC fork with a Fox Performance Float EVOL RE:aktiv shock. There's a SRAM GX Eagle 12-speed drivetrain, aTruvativ Descendant 6k crank and SRAM Guide R brakes. This bike gets a pair of SUNringlé Duroc 40 SL wheels and they're shod with a pair of Bontrager XR4 Team Issue, Tubeless Ready tyres with Inner Strength sidewalls and aramid beads. We get a Bontrager Line Dropper on this bike with a 780mm wide alloy bar, also from Bontrager.

Trek Supercaliber

Filling the role of the full suspension cross country bike is the rather unique looking Supercaliber. The standout feature of this bike is its IsoStrut suspension platform. It offers 60mm of fully tunable travel and what makes it special is that it does away with a rocker link thus saving a chunk of weight. The IsoStrut is also a structural feature of the frame which Trek says prevents twisting, flex and deflection which the brand claims offers a more direct power transfer. The whole range of Supercalibers feature carbon frames rolling on 29" hoops, Straight Shot downtube and the Knock Block. The geometry on this bike sees a 69° head angle, 74° seat tube angle and a 430mm chainstay. The reach of a large frame measures in at 455mm. There are six sizes from S to XXL and an ML size which gets a longer top tube than the M. Up front there's 100mm of travel.

Supercaliber 9.9 XX1 AXS

The Supercaliber 9.9 XX1 AXS takes the crown as Trek's most expensive mountain bike. It comes dripping with top-shelf kit such as the RockShox SID SL Ultimate with a Charger Race Day damper and a Fox Factory IsoStrut shock. This bike gets SRAMs XX1 Eagle AXS wireless drivetrain with the carbon crank and SRAM Level Ultimate brakes. It rolls on a pair of Bontrager Kovee XXX OCLV carbon wheels and they're wrapped with a set of 2.2" Bontrager XR2 Team Issue, tubeless ready tyres with Inner Strength Sidewalls and aramid beads. Then the finishing kit also comes from Bontrager and the line of carbon components, including a 720mm wide handlebar.

Supercaliber XX1 & XTR

Next up the Supercaliber 9.9 XX1 and XTR get all of the same kit as the priciest model but they drop the fancy wireless shifting. Instead, there's a choice of either a SRAM XX1 Eagle drivetrain with SRAM Level Ultimate brakes or a Shimano XTR drivetrain with XTR M9100 brakes.

Supercaliber XT & GX

Seeing a considerable saving from the rest of the range, the Supercaliber 9.8 GX and XT models get a downgraded Fox Performance 32 Step-Cast fork with a GRIP2 damper. There's also that IsoStrut suspension also provided by Fox but this model doesn't get that sleek Kashima coating, coming from the brands Performance line-up. These models come with a choice of either a SRAM GX Eagle 12-speed groupset with both choices coming kitted with Shimano Deore XT M8100 brakes. Here we get a pair of Bontrager Kovee Pro 30 carbon wheels, then the rest of the kit is the same as what you would get on the other bikes.

Supercaliber 9.7

The Supercaliber 9.7 is the most budget-friendly option in the range. It's still built around that OCLV carbon frame and the Performance level IsoStrut shock but gets a RockShox Reba RL fork. This one is driven by a SRAM NX Eagle drivetrain and it's stopped by brakes from Shimano with the MT501 levers and MT500 calipers. This model gets slightly narrower Bontrager Kovee Elite 23 carbon wheels with the same XR2 tyres but the rest of the bike comes from Bontrager's alloy line of kit.

Trek Procaliber

The Procaliber is Trek's lightweight cross country hardtail. Compared to the Supercaliber it presents a mighty cash saving if you're looking for a race-ready XC bike. That doesn't mean that it's not without some cool tech, however. The Supercaliber benefits from what Trek calls the IsoSpeed decoupler which allows the set tube to rotate independently from the top tube to seatstay junction which Trek says offers some vertical compliance without sacrificing pedalling efficiency. As with the rest of the range, this bike gets the Straight Shot downtube and Knock Block too. Each bike in the Supercaliber line up comes with a carbon frame which rolls on 29" wheels and can fit up to 2.4" rubber. Here we see a 68.8° head angle, a 73.8° seat tube angle and 432mm a chainstay. A large frame benefits from a 450mm reach and there are six sizes, from S up to XL, including an ML size which gets a longer top tube than the M. The Procaliber gets 100mm of suspension.

Procaliber 9.8

Built around an OCLV carbon frame the Procaliber 9.8 comes with a Fox Performance 32 Step-Cast fork with a GRIP damper. It's driven by a Shimano XT drivetrain with Deore XT M8100 brakes but this one gets an e*thirteen TRS Race Carbon crank. The wheels here are a pair of Bontrager Kovee Elite 30 carbon wheels and there's a pair of Bontrager 2.2" XR2 Team Issue, tubeless-ready tyres with Inner Strength sidewalls and aramid beads. The rest of the kit comes from Bontrager too, with a 720mm wide carbon handlebar.

Procaliber 9.7

This model comes equipped with a RockShox Reba RL Solo Air and a SRAM GX Eagle 12-speed drivetrain with Shimano MT501 brake levers hosed to MT500 calipers. This bike gets Bontrager's Kovee Elite 23 wheels, then the rest of the bike matches the 9.8 model.

Procaliber 9.6

On the 9.6 model of the Procaliber you'll get a RockShox Recon Gold RL and a mixture of Shimano kit making up the drivetrain. There's an SLX M7100 shifter and an XT M8100 derailleur. With this model there's the move over to alloy wheels, they come from Bontrager and the Kovee's. Then there are the same tyres as the rest of the range and an all-alloy finishing kit from Bontrager.

Procaliber 9.5

Finally the Procaliber line-up is rounded off with the 9.5. Even as the cheapest bike, it still gets that OCLV carbon frame but sees a RockShox Judy SL fork. There's a full Shimano Deore 12-speed drivetrain with Shimano MT200 brakes. Then the rest of the bike features the same kit that you'll find on the 9.6 model.

Trek X-Caliber

If you're looking for a race-ready cross country bike but you're on a budget, the X-Caliber is the bike for you. Accommodating for its affordable price point is an aluminium frame rather than the carbon you'll find on its pricier sibling, the Procaliber. The X-Caliber comes kitted with rack mounts, so it's bike-packing ready, along with a mount for a kickstand. All frames feature internal routing and they all come kitted with Trek's Blendr stem. The X-Caliber comes with either 650b wheels on sizes XS and S with all larger bikes (up to XXL) roll on 29" hoops. As for the geometry, there's a 73° effective seat tube angle on sizes M and up while the smaller two sizes get a 73.5° effective seat tube angle. Then there's a 69.5° head tube angle (S and XSs get a 69.3° HA) and a 438mm chainstay on M and up, and a 425mm chainstay on the smaller bikes. Sizes S to XL get 100mm of travel leaving XS with just 80mm. Although, the frame will accept a maximum of a 120mm fork while the XS can accept a 100mm fork.

X-Caliber 9

Heading up the range, the X-Caliber 9 gets a RockShox Judy Silver Solo Air with a TurnKey remote lockout. This bike gets a Shimano SLX M7100 12-speed drivetrain with Shimano brakes made up of an MT401 lever and an MT400 caliper. The wheels on this one are a pair of Bontrager Kovees and they're wrapped with a pair of Bontrager XR3s in the 2.3" width on all sizes. The finishing kit comes from Bontrager too with an alloy bar, stem, and seat post.

X-Caliber 8

The middle of the range X-Caliber 8 comes with a RockShox Judy SL Solo Air fork with a SRAM SX Eagle 12-speed drivetrain. Stopping the bike is a pair of MT200 brakes from Shimano. As for the wheels, the rims come from Bontrager with a pair of kovees and they're laced to Formula DCL-141Q hubs. Then the rest of the bike is the same as the X-Caliber 9.

X-Caliber 7

The X-Caliber 7 gets much of the same kit as the X-Caliber 8 with the only difference in spec being its Shimano Deore 10-speed drivetrain.

Trek Roscoe

If you're looking for a trail orientated hardtail, the Roscoe fits the bill. Each build comes properly sorted with dropper posts, 120mm of travel (size S gets 100mm), 1x drivetrains and alloy frames. The bike also rolls on 650b+ wheels and tyres. They all feature internal cable routing, rack and kickstand mounts too. Onto the geometry, the Roscoe sees a 67.3° head angle, a 70.8° effective seat tube angle (with the medium frame getting a 70.7° effective seat angle and the S and XS getting 71.2° and 71.1° angles respectively), and a large frame gets a 428mm reach. As a 650b+ bike, it can run either 27.5x2.8" or 29x2.4" rubber.

On the Roscoe 8, you'll find a RockShox 35 Gold RL fork with a SRAM NX Eagle 12-speed drivetrain with Shimano brakes in the form of the MT501 lever paired with an MT500 caliper. It's worth noting that the fork comes with a flexy QR axle. The wheels here are made of rims from Bontrager and the Line 40s with a Bontrager hub at the front and a Formula hub at the rear. This bike gets a pair of Maxxis Rekon tubeless tyres with a 2.8" width and then the rest of the kit comes from Bontrager and the alloy range apart from the dropper post, which comes from TranzX with the JD-YSP18.

The Roscoe 7 benefits from most of the same kit as the 8, but this one gets a SRAM SX Eagle 12-speed drivetrain and Shimano MT200 brakes.

On the cheapest Roscoe 6 you'll get an SR Suntour XCM 32 coil sprung fork with a Shimano Deore 10-speed drivetrain and MT200 brakes. This bike then rolls on Alex MD35 rims and Formula DC hubs which get a pair of Kenda Havok, wire beaded, 2.8" tyres. As for the rest of the build, that's just the same as the rest of the range.

Trek Marlin

If a sub £1k cross country, everyday bike is more your speed then it's worth checking out the Trek Marlin. Each bike in the range comes with an alloy frame and a fork with 100mm of travel (XS frames get 80mm). There are also rack and stand mounts, the Blendr stem, and internal cable routing. XS and S sizes roll on 650b wheels while sizes M to XXL get 29" hoops. On the Marlin, you'll get an effective seat tube angle of 73.5° on the XS and S frame while everything else benefits from a 71.9° effective seat tube angle. As for the head angle, on the smaller sizes it'll measure in at 69.3° and from M upwards it's a couple of degrees steeper at 69.5°. All frame sizes share a 438mm chainstay length and a large frame gets a 451mm reach.

The Marlin 7 comes kitted with a RockShox Judy coil sprung fork with a Shimano Deore 10-speed drivetrain and Shimano MT200 disc brakes. The wheels are made of Bontrager Kovee rims laced to Formula DC hubs and they're wrapped with a pair of Bontrager XR2 Comp 2.2" tyres with wire beads. The rest of the bike comes with Bontrager's own finishing kit.

Trek Farley

Perhaps fat bikes are more your things. Allow me to introduce the Farley. There are two in the 2021 range with an alloy and a carbon option which, of course, roll on 4.5" tyres. Both bikes come with a dropper post, horizontal sliding dropouts, ideal for single speed setups and tubeless-ready tyres. As for the geometry, the Farley gets a 69° head angle, a 73° effective seat tube angle and a 455mm chainstay. The reach on a large is 441mm and there are four sizes available, from S to XL. 

The Farley 9.6 gets an OCLV carbon frame with a Bontrager Haru OCLV fork. The drivetrain on this bike comes from SRAM and the GX Eagle 12-speed shifting. As for wheels, they're Sunringle Mulefut 80 SL rims laced to Bontrager alloy hubs. Those are wrapped in a pair of Bontrager Barbegazi Team Issue, tubeless-ready tyres with inner strength sidewalls and aramid beads. The dropper kitted here is a TransX JD-YSP18 and the rest of the kit comes from Bontrager with a 750mm wide bar.

The Farley 5 is Trek's best value fat bike and it's built around an alloy frame. It gets a Shimano Deore M4100 10-speed drivetrain with SRAM Level brakes and there's a Race Face crank. It gets the same wheels as the 9.6 but the tyres here are a pair of Bontrager Gnarwhals. The rest of the kit is the same as the 9.6. It's worth mentioning that while the Farley 5 comes with a rigid fork, it'll happily accommodate a 100mm travel suspension fork.

Trek Session

The Session needs no introduction, but it's the brand's 650b downhill bike. There's only one model in the 2021 range which is built around an alloy frame. It gets Trek's Active Braking Pivot and the geometry adjusting Mino-Link. Up front, there's 200mm of travel and at the rear, there's 210mm. In the low setting, the Session gets a 63.6° head angle, a 445mm chainstay and a large frame gets a 426mm reach. There are four sizes, from S to XL and the 8 27.5 model will set you back £4,200

Trek Ticket

Finally, rounding off the Trek range of mountain bike is the Ticket. It's available as the full suspension, Ticket S (pictured) with 100mm of travel and the Ticket DJ, which is the hardtail version. Both come as a frame only with prices starting from £725, up to £1,400.

No 2021 Trek Stache | Discontinued

• Add to quote

I've read here on MTBR and other forums that there will be no 2021 Trek Stache. I think the Stache is one of the funnest bikes I've ever ridden and I'm sad they're discontinuing it. Here's my Stache build:  

Complete bikes are gone. Frame-only option still exists.  

I can't even find frames any more on the Trek USA site.  

I've got a 2016 ill sell  

*most fun  

They are fun bikes for sure. My friend has one and it seems to work well for him. I liked the plus tire feel. Kind of like having full suspension. Heavy though!!  

I'm hoping they are discontinuing this only because of production bottlenecks, and will have a new 29+ model in their lineup 2022 when (let's hope) production is more steady again.  

Trek now has a big gap in their lineup - A decent trail 29 hardtail. Filled by competitors with bikes such as the Specialized Fuse, Merida Big.Trail, Norco Fluid HT, Giant Fathom, Ragleys, Canyon Stoic, and heaps of others, etc, etc. The current model Trek Roscoe is an over-forked XC toy bike with QR dropout rear axle and super slack seat angle. Its still probably selling up a storm given limited supply...

I was very disappointed to see the Stache removed as well and even considered buying a frame to keep as a spare in case anything happened to mine but I see even that's not an option as they're gone from the UK site. I've had my Stache five years now and still love it, never come another bike I've preferred to ride. The Roscoes do seem incredibly popular and were selling out long before the pandemic and in our local MTB group where there's no two bikes the same, there's something like four Roscoe's though. While I don't see the Roscoe as a rival to the Stache on the other hand I've very rarely seen any other Staches and do tend to see a reasonable amount of their other models.

Trek Does It All with the New Madone

Trek’s new eighth-generation Madone is lightweight, aerodynamic, and fast—the road bike raced by Lidl-Trek in the 2024 Tour de France.

Takeaway: For the eighth iteration of its legendary Madone road bike, Trek blended the low weight of the Emonda with the aerodynamics of the seventh-generation Madone. The result is a light, stiff, and fast all-around race bike. While the flagship SLR9 costs over $13,000, base-level Madon SL models start at $3,500.

Price as Tested: $13,500 Weight: 15.3 lbs (Size M, bottle cages, computer mount, no pedals)

Trek Madone SLR 9 AXS Gen 8

Jordan Roessingh, Director for Road Bikes at Trek, candidly confirmed that the new Madone actually started life as the next Émonda. “We constantly get the same feedback from our pro riders,” Roessingh said. “They tell us that they love how fast the Madone is, but could we make it lighter or they love how light the Émonda is, but could we make it more aero?”

Trek set out to make a more aerodynamic Émonda, and what they ended up with was a bike that had the same frame weight as the Émonda but was as quick as the Madone against the wind.

When your aero bike is as light as your climbing bike, or your climbing bike is as aero as your aero bike, there doesn’t seem to be a point to having two bikes anymore. So, while fans of the Émonda might be sad to see the bike go, it makes way for the return of the Madone as the ultimate road racing bike in Trek’s lineup. And this feels right, given the rich history of the Madone name.

Since it launched in 2003, the Madone name has always designated Trek’s fastest drop-bar race bike. That has meant different things at different points, with older models of the Madone leaning heavily on low weight and high stiffness while more recent models became all-out aero. Now that Trek returns the Madone to a do-it-all role, is it the best road racing bike Trek can make?

After spending the last two months riding the new Madone 8, my short answer is yes.

The new bike delivers the performance I expect from a five-figure top-of-line road bike made by a brand like Trek. For the steep price of entry, you get a bike that manages to be damn near perfect in terms of weight, stiffness, and road manners. And while all of that is important, it would matter little to bike racers (for whom the Madone is explicitly designed) if it wasn’t also fast.

Based on Trek’s provided data and my testing, the new Madone is definitely fast. But that declaration comes with a long list of caveats.

Speed is Aerodynamics In 2024

In 2011, Specialized first told us that “Aero is everything.” Knowing what I know now about the importance of aerodynamics in the context of racing, they certainly weren’t wrong. But marketing slogans are made to be catchy and concise and “Aero is everything until you build a bike that’s really heavy and doesn’t ride all that well. So maybe a bike that prioritizes aerodynamics without sacrificing weight and ride quality would be better,” does not quite roll off the tongue as easily.

Trek claims that the new Madone is as fast as the previous generation and is heaps quicker than the Émonda. The strategy to achieve this aerodynamic performance is called “Full System Foil,” where the bike is viewed not only as a cross-section of its tube shapes but as a much larger airfoil shape that includes the water bottles and wheels.

This isn’t a particularly new or earth-shattering concept. Manufacturers have designed (or at least tested) their frames around specific wheels (usually their own) for a while now. Using water bottles to fill the space between the down tube and the seat tube to smooth the airflow over a frame is also not new. It has been done on time trial and triathlon bikes for years. BMC has done it on their aero-focused time machine road bike since 2018. Cannondale recently introduced aerodynamic water bottles and cages on its all-around race bike, the SuperSix Evo , in 2023.

The cynical reading of what Trek does with the new Madone and its aerodynamic performance claims relative to the previous (and more obviously aerodynamic Madone Gen 7) is that directly comparing the two bikes is not apples-to-apples.

Trek’s claimed figures use a Madone 8 with the brand’s new aero bottles versus a Madone 7 with round bidons. In this comparison, the new Madone (at straighter yaw angles) is slightly faster than the outgoing Madone. At higher yaw angles (beyond 10º), the deeper frame tubes of the Madone 7 make it quicker than the new Madone. And when comparing the new and old Madone, with both bikes using round bottles, the results flip. According to Trek, the Madone 7 is about 1.6 watts more slippery at 22 mph.

It’s also worth dwelling for a moment on the yaw angle differences. My colleague Matt Phillips pointed this out in his review of the Specialized Tarmac SL8 , another new bike that balances optimizing aerodynamics, ride comfort, and weight. In that review, Matt points out that a rider’s speed affects the wind angles they encounter. Pro riders naturally encounter more direct (low yaw) wind angles because they (typically) ride much faster than amateur riders. Riders moving at slower average speeds will more likely encounter higher wind angles.

Trek’s aerodynamic claims for the Madone 8 are based on a rider moving at 22 mph. That is more real-world than Specialized data for the Tarmac SL8, which is based on someone moving at 28 mph.

Still, 22 mph is plenty fast for a lot of people. My rides typically average about 18 mph. At slower speeds, where the rider is more likely to encounter higher yaw angles of wind, the previous Madone will likely be faster. Strap the new Aero bottles on it, and it will almost certainly be quicker than the new Madone regardless of the wind derection.

But the gains in the Madone 8’s aerodynamics are not only down to the water bottles. Trek also introduced a new handlebar, which, when tested in isolation (without a rider on the bike), is slower than the previous handlebar. However, as part of the system with a rider on the bike, the new taller and blunter profile measures faster as it helps to smooth the airflow over the rider’s legs.

If I stop being a cycling media cynic for a minute, I can see where Trek comes from in how it designed the new Madone. Sure, there is broad acceptance across cycling to the benefits of aerodynamics, yet despite this, riders still love lightweight and snappy-feeling bicycles. With the design and packaging of the new Madone, Trek can say that the new bike is faster.

However, the issue with judging aerodynamic gains is the numerous “it depends” moments. Most of these depend on how each individual bike is equipped for testing. Using aero bottles for one frame but round ones for another is obvious, but even something less apparent, like a different handlebar shape or a different-sized rider (if you’re testing with a rider), could give different results.

To put it in perspective, Trek claims the new bike is 1.6 watts faster at 22 mph. That’s not nothing. But it’s also fair to point to the basically square downtube of the new Madone and say that Trek perhaps has left some potential aerodynamic gains on the table to make a lighter and better riding bike. And to be perfectly honest, I’m not that upset about it.

New Sizing, Similar Geometry

Long-time Trek fans will remember when the brand offered two different fits on its top-of-the-line road bikes: H1 fit, designed for pro athletes, and H2 for the riding public. This gave riders a choice of stack and reach figures. The H1 and H2 fits were eventually consolidated into what Trek dubbed H1.5. But the H1.5 designation didn’t make a ton of sense (since it referred to a geometry philosophy that no longer existed), so Trek rebranded H1.5 into “Road Race” geometry.

This rebrand comes with Trek changing its numeral sizing (51, 53, 55, etc) to T-shirt sizing (XS, S, M, etc). This is another change that makes sense to me as modern bikes rarely have a tube on them that actually measures close to their designated size number.

The big geometry shake-up with the new Madone is that Trek reduced the bike from eight sizes on the Madone 7 to six. This was accomplished by merging the 52cm and 54cm sizes into a Medium option and the 60cm and 62cm sizes into an Extra Large. Brands often reduce model options at each end of the size spectrum (to the detriment of shorter or taller riders), so it’s unsurprising that Trek merged the 60cm and 62cm. But it surprised me to see the 52cm and 54cm sizes combined.

Looking closer at the two sizes from the previous generation Madone, I was shocked at how close they were to each other. The bikes had only a 3mm difference in reach and an 8mm difference in stack. The new frame size has a few millimeters more stack than the old 54cm and 1mm more reach than the old 52cm.

I’m a rider who often chooses between these two sizes. For example, I’m happy to ride 54cm bikes from Specialized while I opt for 52cm frames from other brands like Enve or a size S from Giant. The new Medium-sized Madone I tested worked very well when paired with a 110mm stem and a zero-offset seatpost.

Still, I expect the merging of two sizes right in the middle of the size range, despite how close they are in practice, will cause some consternation for riders.

Models and Pricing

Trek offers the new Madone in nine complete bike builds and two frameset options. These are split between the more affordable Madone SL and a higher-end Madone SLR. Both bikes share the same frame shape and geometry, but the Madone SL uses a heavier 500 series OCLV carbon compared to the Madone SLR’s 900 series.

All versions of the Madone SL come equipped with a standard two-piece bar and stem. Riders who want the full aero benefits of the new bike will have to buy the aero bottles separately. A single bottle and cage set is $100, with replacement bottles at $25 each.

Four complete Madone SL bikes are offered, starting with the Madone SL 5 ($3,500), which features mechanical shifting using Shimano’s 12-speed 105.

The Madone SL 6 costs $5,500 and comes with a Shimano 105 Di2 groupset and Bontrager Aeolus Elite 35 carbon wheels. There is also a SRAM Rival AXS build of the Madone SL 6, which costs an additional $500.

At the top of the SL range is the Madone SL 7 ($6,500). This model upgrades to a Shimano Ultegra Di2 groupset, plus it uses a carbon handlebar and the deeper Bontrager Aeolus Pro 51 carbon wheels.

Next on the price pyramid is the Madone SLR 7 ($9,000). It features the same build kit as the SL 7, but for the extra $2,500, riders get the lighter-weight SLR frame, the aero bottles, nicer tires, and the one-piece RSL bar/stem. For $500 more, riders can opt for a SRAM Force AXS version of the same bike.

Finally, there are the SLR 9 flagship options. Riders can choose a Shimano Dura-Ace Di2 bike for $13,000 or one with the new SRAM Red AXS for $13,500.

Riders looking to do a frame-up build can pick between the Madone SL frameset, which costs $3,000, and the Madone SLR frameset at $6,000.

Ride Impressions

I don’t think there’s any point in dancing around it, Trek made a good bike with the latest version of the Madone—which is hardly a surprise. When you’re twenty-one years into developing a platform and are on the eighth version of it, I’m not going to say it’s impossible to make it bad, but it’s certainly difficult. This expertise, combined with wider tires that make current road racing bikes ride more comfortably than bikes from only a few years prior, I expected the new Madone to impress. And it delivered.

The new Madone is a big step forward from the previous generation Madone 7 in its enjoyability. Stomp on the pedals and the new Madone has plenty of snap, but crucially, it is vastly superior in seated comfort compared to the 7.

I complained about Trek shipping the previous Madone with 25mm wide tires, which honestly felt insane to me back in 2022 when I tested the bike. Thankfully, the new Madone ships with 28mm rubber that measures 29.5mm on the Bontrager Aeolus RSL 51 wheels. The wider tires certainly help with how pleasant the new bike feels on the road, but you still wouldn’t mistake the Madone for an endurance bike. This race bike provides excellent road feedback to the rider. You don’t float over the road on the new Madone, but it doesn’t beat you up while riding.

The next big thing I felt about the new Madone was its low weight. I clearly remember testing the Madone 7 (only two years ago), that top-level build with SRAM Red and the same wheels was 16.2 pounds (without pedals, cages, or a computer mount). The new Madone 8 I rode is nearly a pound lighter at 15.3 lbs. And impressively, that weight includes the aero bottle cages and a computer mount (but not pedals).

While we know that, empirically, bike weight has a much smaller impact on performance than we think, a lighter bike still feels awesome. When a brand charges five figures for a road bike, it should be really close to, if not below, the UCI minimum bike weight of 14.99 lbs. The previous generation Madone was never in danger of falling under that weight limit, but the new Madone should comfortably hit it with a lighter set of wheels and one or two other weight weenie changes. The Madone’s low weight and stiffness make it a fun bike to ride uphill.

Thankfully, Trek did not change the Madone 8’s handling compared to the previous version. It’s still an exceptionally well-balanced bike. Racers will find steering that, while rapid, isn’t a handful. The Madone is very stable at speed while remaining exceptionally reactive to rider inputs.

I logged quite a few miles on the new Madone and while I know that sensations are not statistics, the new Madone feels very fast. On a flat and fast weekly group ride I do, I found myself rolling off the front of the group when it was my turn to take a pull at the front. Despite the lack of deep aero tubes, the new Madone certainly has the sensation of speed that the best aero race bikes often possess. It’s best described as feeling like you’re riding with a permanent tailwind.

Conclusions on the New Madone

Combining two bikes into one is a surefire way to leave some cyclists wanting more. Some will want a more aerodynamic Madone. While others will rightly point out that Trek could have made an even lighter bike. However, the demands of modern racing often require a bike that is both aerodynamic and lightweight.

I appreciate the raw speed of an all-out aero bike. Yet bikes like that are never at the top of my dream bike ownership list. Instead, I’ve gravitated to more all-around performers, if not straight-up weight weenie dream bikes like the Specialized Aethos .

This is probably why I don’t mind Trek going with the happy medium. Even though a true Émonda rider would have wanted Trek to make the Émonda platform lighter versus more aero, I agree with Trek that the majority of Madone 7 riders—and most road riders in general—will appreciate the new Madone’s big weight reduction without taking a massive aerodynamic hit (at least on paper).

For riders with the taste and budget for this bike, the new Madone won’t disappoint. It’s a great road bike capable of competing at the highest level while offering an alternative to other high-end, do-it-all lightweight aero bikes, like the Pinarello Dogma F, Specialized Tarmac SL8, or Factor’s Ostro Vam. For cyclists seeking a bike like this but on a more limited budget, Trek offers one of the lowest-priced entry points into a high-end race bike its $3,500 Madone SL 5.

So, while the eighth-generation Madone might not be for everyone, Trek at least offers its latest race bike in a broader range of prices than the previous version, and that’s something worth celebrating.

Notes From the Field

Random observations from my time testing the bike..

• Considering how important the new bottles are to the aero performance of the new Madone, it’s worth discussing them. There is an adjustment time to become accustomed to getting them in and out of the aero cages. The actual hold feels extremely secure. If anything, they are a bit harder to get in and out than I want them to be, but I got used to them after a few weeks of riding. My only real gripe with them is the valve. It takes more force to open and close than I want. Plus, the flow isn’t that great. A minor annoyance is that you can’t stand the bottles on their end to fill them. Fortunately, the aero cages can hold a traditional round bottle, or you can ditch the bottle and cages altogether if the extra aero gains aren’t that important to you.
• Given I recently wrote a story on every bike being raced in the 2024 Tour de France , including all 18 of the World Tour teams, I’m rather confident that the new Madone is the only bike currently using a UDH derailleur hanger in the World Tour. This is great for everyday riders as it means a spare hanger should never be all that hard to find and this generation of Madone should be future-proofed for whatever drivetrain SRAM might have in the future.
• While the battle against through-the-headset cable routing has been lost, Trek at least makes the latest Madone a little easier to live with. Trek offers separate headset and spacer options to match its RSL Aero one-piece bar/stem and its RCS Pro two-piece cockpit, but there is also a headset cap that allows riders to run whatever handlebar and stem they want. Trek even offers an alternative top cap that lets riders run a round spacer on top of the RSL Aero bar. This means riders can adjust their bar height without cutting brake hoses or trimming the steerer tube.
• The included computer mount does not allow you to adjust the angle of your computer, which is annoying. Otherwise, it’s a tidy mount and a big improvement over the one used on the Madone 7.
• The new saddle clamp design is a big highlight. It’s secure and features independent adjustments for the angle and fore/aft adjustments, which is a big improvement over Trek’s previous single bolt design.
• The RSL Aero one-piece cockpit won’t please everyone. Personally, I found it quite comfy in both reach and drop shape. However, the back sweep on the tops might annoy some riders who prefer a straighter top section and spend lots of time with their hands there.
