Trek Roscoe 9 Mountain Bike
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.

Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.
