Trek Roscoe 7 (Gen 4) Trail Mountain Bike 2026

Roscoe 7 is a wild and playful hardtail that's ready to rip anywhere from rowdy singletrack to dirt jumps. Its Alpha Gold 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 stopping power that doesn't break the bank.
