It's right for you if...
You want to have fun. You're searching for a playful trail bike with high-quality parts so that when you're out on the trail, the only thing you have to worry about is your face hurting from smiling too much.
The tech you get
A lightweight aluminum frame, a 140mm RockShox 35 Gold fork with a lockout, a SRAM NX Eagle 1x12 drivetrain with a wide range of gears for climbing, powerful 4-piston brakes, and a dropper post for room to move around on the bike on descents, corners, and jumps. Plus, fast-rolling 29er wheels with a 108-tooth Rapid Drive hub for instant engagement, and wide, grippy 2.6" tires.
The final word
High-quality parts, high quality fun. With an upgraded fork, upgraded wheels, a wide range of gears, and 4-piston brakes this bike takes trail riding shenanigans seriously.
favorite_borderWhy you'll love it
- 29er wheels and wide 2.6" tires make for a grippy, confident, and fast-rolling ride
- The dropper post lets you lower your saddle on the fly so it's out of the way on descents
- The RockShox fork's Solo Air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
- The fork’s lockout feature lets you temporarily lock the suspension for better efficiency on flat stretches
Ready to get rowdy
With 140mm front travel, trail-smashing 29-inch wheels, and dialed-for-dirt frame features, Roscoe is ready to get rowdy on your favorite rides.
Progressive trail geometry
A long reach, slack head angle, steep seat angle, and short chain stays combine for a ride that's confidence inspiring, yet still nimble and fun.
The strong quiet type
Roscoe stays well protected with a double-sided chainstay guard, tough downtube guard, and internal cable guides that help your ride stay quiet, even over rough trails.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
International Standard Chain Guide mounts offer easy chain guide installation and adjustment.
Threaded bottom bracket
More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
