2025 | Roscoe 8 Gen 4 - The Bike Shop

Product Info

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.

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.

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.

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.
