The Roscoe 8 is a trail hardtail for anyone looking to have some serious fun on the dirt. 29er wagon wheels smooth out rocks and roots, grippy 2.6″ tyres give you a boost in traction and a 140 mm 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 aluminium frame, a 140 mm RockShox 35 Gold fork with a lockout, a SRAM NX Eagle 1×12 drivetrain with a wide range of gears for climbing, powerful 4-piston brakes and a dropper post for room to move around on the bike 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″ tyres.
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.
The Walkthrough
Why you’ll love it
- 29er wheels and wide 2.6″ tyres 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
