Plus, a dropper post, a SRAM NX Eagle 1x12 drivetrain, and Shimano hydraulic disc brakes.

favorite_borderWhy you'll love it

  1. It's more fun to be a better rider: Roscoe is so stable and forgiving, it's like an instant ability upgrade
  2. Even when the trail gets rough, the wide 27.5x2.8˝ tires can deliver confidence, traction, and stability
  3. The dropper post lets you lower your saddle on the fly so it's out of the way on descents
  4. The RockShox fork's Solo Air spring can easily be adjusted for a specific rider weight, and it's lighter than a coil spring


Features

Built for fun

Roscoe is a confidence-inspiring trail hardtail with stable handling, robust parts, and a longer-travel fork that gives you more control over bigger hits. Built to party with 1x drivetrains and dropper posts, these models are perfect for anyone who values fun over fast.

27.5 Plus traction

Better traction gives you more confidence. Roscoe's extra-wide 27.5 Plus tires give you more grip and overall stability so you can roll over anything with confidence.

High tech frame

The Alpha Gold Aluminum frame is packed with features that make your ride better. A tapered head tube gives you more precise, confident handling on the front end, while Boost 141 rear hub spacing gives you shorter chainstays for more nimble handling out back.
