THIS PRODUCT CANNOT BE SHIPPED. YOU MUST COME TO OUR RETAIL STORE FOR DELIVERY.

Roscoe 8 is a rowdy hardtail built to hunt for side hits and dive into the steep stuff . Its Alpha Gold Aluminum frame pairs with a Fox Rhythm 36 fork (150mm travel) to soak up rough and chunky trail debris. It delivers plenty of gears for punchy climbs, thanks to a 12-speed Shimano Deore drivetrain, and stop-on-a-dime braking power from 4-piston Shimano M6100 hydraulic disc brakes.
