Ready to get rowdy
With 150mm front travel, trail-smashing 29-inch wheels, and dialed-for-dirt frame features, Roscoe is ready to get rowdy on your favorite rides.
-
Rock Solid
The bolt on downtube guard will stay put even after ripping though a chucky trail, keeping your bike quiet and protected.
-
Integrated storage
The frame bag is made from a recycled ripstop polyester with an eco friendly DWR coating on the outside that is water resistant, with plenty of room to stash everything from snacks to safety supplies.
-
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.

A better way to produce aluminum
Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
