Features
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.
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.
Boost148/110
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 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
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.
