"Roscoe is a plus-tired hardtail that's decked out with all the modern luxuries you could want.

Not only were we impressed by its handling, it featured all the modern conveniences, including chunky 2.8 tires and a dropper post."

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.
Air spring fork
Air springs are a lot lighter and more adjustable than coil springs. You can adjust the air pressure to match your rider weight, so you get the best ride.
Tubeless Ready
Tubeless Ready rims and tyres make it easy to ditch the tubes so you get better traction, fewer flats and less weight. The rim strips are already installed; just add TLR valves and sealant.

Dropper post
Use the remote lever to lower your saddle so it's out of your way when you're descending and cornering.
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.
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.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
