Trek Roscoe 7 Gen 4
Trek / Trail Mountain Bikes
A trail hardtail made for fun.
Roscoe 7 is a wild and playful hardtail that's ready to rip anywhere from rowdy singletrack to dirt jumps. Its Alpha Platinum Aluminum frame pairs capable geometry with a RockShox Recon Silver fork (150mm travel) for gobbling up rocks, while a 10-speed Shimano CUES drivetrain provides low-maintenance, clean shifting. It's finished with 2-piston Shimano MT200 hydraulic disc brakes for reliable all-weather stopping power.

Questions are welcome. No pressure, no bike jargon required.
The ride, not just the specs
Roscoe is a hardtail built for having fun on the trail. It's tough, easy to look after, and grippy enough to try new things.
It's a great bike for learning skills, riding with friends, and lapping your local trails.
What makes it special
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.
The bolt on downtube guard will stay put even after ripping though a chucky trail, keeping your bike quiet and protected.
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.
