Roscoe 8 is a trail hardtail for anyone looking to have some serious fun out in the dirt. 29er wheels, grippy 2.6" tires, and a 140mm suspension fork make it a blast on every trail, from packed singletrack to the loose stuff. It's a laid-back trail mountain bike dressed in a high-quality spec that's ready to party.
It's right for you if...
You want to have fun. You're searching for a playful trail bike with high-quality parts so that when you're out on the trail, the only thing you have to worry about is your face hurting from smiling too much.
The tech you get
A lightweight aluminum frame, a 140mm RockShox 35 Gold fork with a lockout, a SRAM NX Eagle 1x12 drivetrain with a wide range of gears for climbing, powerful 4-piston brakes, and a dropper post for room to get low on descents, corners, and jumps. Plus, fast-rolling 29er wheels with a 108-tooth Rapid Drive hub for instant engagement and wide, grippy 2.6" tires.
The final word
High-quality parts, high quality fun. With an upgraded fork, upgraded wheels, a wide range of gears, and 4-piston brakes this bike takes trail-riding shenanigans seriously.
- 29er wheels and wide, 2.6" tires make for a grippy, confident, and fast-rolling ride
- The dropper post lets you lower your saddle on the fly, so it's out of the way on descents
- The RockShox fork's Solo Air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring
- The fork’s lockout feature lets you temporarily lock the suspension for better efficiency on flat stretches
