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 tyres give you more grip and overall stability so you can roll over anything with confidence.
High tech frame
The Alpha Gold Aluminuum 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 at the back.
Suspension lockout
Locked suspension means your fork remains inactive, increasing pedalling efficiency. Perfect for extended road sections where efficiency is more important than bump absorption.
Dropper post
Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
Rack mounts
Going for a long ride? Rack mounts make carrying accessories a breeze.
Rear kickstand mount
Chainstay mounts make it easy to install a rear kickstand that stays out of your way and supports bikes of all sizes. No more laying or leaning.
