Ready to get rowdy
With 140 mm front travel, trail-smashing 29-inch wheels, and dialled-for-dirt frame features, the Roscoe is ready to get rowdy on your favourite 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
The 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.
Upgrade your pedals and love your bike more
Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
Complete Tubeless System
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. You're ready to roll straight out of the box with the included TLR rim strips, valves and sealant.

Shop nowBoost148/110
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 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
Dropper post
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.
ISCG mounts
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.
