Roscoe looks great on paper but it’s disappointing on the trail
Super wide size range
Dropper post
Tapered head tube
Potential plus tire gains
Awful fork
Outdated frame
Very heavy
Cable rattle
Numb brakes
Wet hating, tubed plus tires

As a gnarly trail shredding bike, it won’t surprise anyone that the Trek Roscoe is biased in favour of the rowdier type of riding.
Nov 2021 · Luke Marshall
The Roscoe’s a well-rounded package that delivers an engaging ride, but with a few compromises
Lots of frame sizes to choose from
Shimano Deore gears work well
Best frame protection on test
Wide tyres can feel vague and roll at high speeds
Weak brakes compared to others
TranzX dropper post was sticky

The Trek Roscoe 9is a killer offering for riders wanting an all-around hardtail ripper with a balanced geo and solid build spec.
Surprisingly capable
Balanced geometry
Comfortable climbing position
Reasonable price
Minor spec niggles
Sore ankles

We know trickle-down technology, but trickle-down geometry is far too rare. the new Trek Roscoe brings the shred to the masses.

The 2022 Trek Roscoe gets 29" wheels, modern trail geometry update and a 140mm fork, evolving into a progressive hardtail mountain bike

Now in its third year of production, the Trek Roscoe 8 is a Plus tyred trail-hardtail that’s decked out with all the modern luxuries you could want.
Grip, comfort and control.

Trek's Roscoe 9 marries an aluminium frame with trail riding orientated geometry to chubby 2.8" Plus tyres on 27.5" rims. While it doesn't jam in as much value as direct sales rivals, it more than makes up for that with a fun, refined ride and coherent kit list.
