Editor’s Note: In the original version of this post, we stated that the updated Trek Roscoe no longer uses Knock Block. In fact, the previous Roscoe frames didn’t use it, or have need for its use, either.
The extremely popular Trek Roscoe hardtail mountain bike has received an overhaul for 2022. Upgrading from 27.5″+ to a 29er and rocking a 140mm travel fork, the Roscoe now sports a rather more modern trail geometry… longer, lower, slacker, you get the point, right? There are now 6 sizes available from an XS (which keeps the 27.5″+ wheels) and 29ers running from S-XL, with prices starting from a very affordable $1,699.99. We have everything you need to know about the 2022 Trek Roscoe right here.
2022 Trek Roscoe
The 2022 Trek Roscoe is an aluminium hardtail mountain bike, now with a modern trail bike geometry. Its most recent evolution swaps out 27.5″+ wheels for faster rolling 29″ wheels, built around an all-new frame with a more progressive geometry that should improve its descending qualities immeasurably. Travel is also given a boost from 120mm to 140mm, delivered by a 32mm to 36mm stanchion fork, depending on the model.
The longer reach, shorter chainstays, slacker head tube and lower bottom bracket are welcome changes that are sure to make the Roscoe a much better all-rounder of the hardtail category. Across the XS-XL frame sizes reach has increased ~20mm and the head angle has slackened significantly to 65°.
Reach on the ML has actually increased massively from 410mm to 455mm. All frame sizes have a straight top tube, with the longer reach allowing for a more gradual angle from the head tube down to the seat tube join. This has actually improved standover as compared to the previous Roscoe. Seat tubes are also slightly shorter, with increased seat post insertion length so that riders can take advantage of a long travel dropper post.
The effective seat tube angle of 74.7° is a major change too, now far more upright than the 70.7° SA of the 2021 iteration. Chainstays are shortened from 438mm to 430mm, though the boost spacing rear end still permits a healthy tire clearance of 29″ x 2.6″.
For the 2022 Roscoe, Trek have moved away from a proportional frame design with a consistent SA and rear-centre length across the frame sizes.

Frame Details
Trek have dropped the 141 Spacing on the Roscoe, upgrading the Roscoe 7, 8 and 9 to Boost 148mm spacing running a thru-axle. The Roscoe 6 is still the previous frame, so still has the 141mm QR axle.
The 2022 Roscoe gets a SRAM UDH hanger, meaning you’ll be able to replace a bent hanger very easily, picking it up from almost any bike shop, not just those that are Trek dealers.
Trek have added an internal cable fastener on the downtube. Cables aren’t fully guided internally, so may have had a tendency to rattle about within the aluminium frame, causing unwanted noise. The cable fastener secures the cables to the inside of the downtube, about half way along it, in an attempt to keep noise to a minimum.
The Roscoe still runs a 73mm threaded bottom bracket that can take a 30mm spindle. The downtube gets dual-density rubber protection to save the frame from rock strikes, while the chainstay gets a double-sided guard to protect against chain slap. Trek have added an ISCG 05 tab for the mounting of a chain guide and bash guard; the top end Roscoe 9 comes with a top guide.
Pricing & Availability
Though you’ll see four models of the 2022 Trek Roscoe for sale, only the Roscoe 7, Roscoe 8 and Roscoe 9 models get this latest geometry and travel update discussed here. The budget option Roscoe 6, retailing at $1,149.99 USD, is a carry over frame from 2021, so still has the ~67.3° head tube angle, 27.5″+ wheels and 120mm travel fork. It runs an SR Suntour XCM 32mm stanchion coil fork, Alex MD35 Rims, a Shimano Deore 10 speed drivetrain, Shimano MT200 2-piston brakes and an aluminium Bontrager finishing kit.
The Roscoe 7 retails at $1,699.99 USD. It gets a RockShox Recon Silver RL 140mm fork, Bontrager Line 30 aluminium wheels, a Shimano Deore 12 speed drivetrain and Shimano MT200 2-piston brakes.
The Roscoe 8 retails at $2,299.99 USD. It features a RockShox 35 Gold RL 140mm travel fork, Bontrager Line 30 wheels, a 12 speed SRAM NX Eagle drivetrain (11-50 cassette), and Shimano’s entry level 4-piston brakes.
The top end 2022 Trek Roscoe 9 will set you back $2,699.99 USD. That hard earned cash gets you a FOX 36 Rhythm 140mm travel fork (yes, it’s a 36, that’s not a typo), Bontrager Line 30 wheelset, a Shimano SLX 12 speed drivetrain (10-51 cassette) and Shimano M6100 4-piston brakes.
