The Roscoe 8 is a trail hardtail for anyone looking to have some serious fun out in the dirt. Its 27.5+ mid-fat tyres, a wide-range 1x12 drivetrain and 120 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 more fun to be a better rider: Roscoe is so stable and forgiving, it's like an instant ability upgrade
    • Even when the trail gets rough, the wide 27.5+ tyres deliver more confidence, traction and stability
    • 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
