It's right for you if...
You like to keep it simple, and you love the fun and connected feel that a hardtail brings to the trail. You want a stout alloy frame that you can trim with your choice of drivetrain, wheels and fork for the ultimate hardtail build.
The tech you get
A sturdy aluminium hardtail frame with internal derailleur and dropper post routing. Comes with an FSA headset. Designed for a threaded BB73. Made for Boost148 29er wheels and a 140 mm or 150 mm suspension fork.
The final word
The Roscoe frame set lets you create your own customised hardtail, with parts you pick to elevate however you love to ride, from techy trails to pump tracks and jump lines.
favorite_borderWhy you'll love it
- Fits up to 2.6" tyres for a grippy, confident and fast-rolling ride
- Add a dropper post for more stability and control on rugged descents
- Long, low and slack – the Roscoe's trail bike geometry gives you confidence for rugged descents.
Ready to get rowdy
With 140 mm front travel, trail-smashing 29-inch wheels, and dialled-for-dirt frame features, the Roscoe is ready to get rowdy on your favourite rides.
Progressive trail geometry
A long reach, slack head angle, steep seat angle and short chain stays combine for a ride that's confidence-inspiring, yet still nimble and fun.
The strong quiet type
The Roscoe stays well protected with a double-sided chainstay guard, tough downtube guard and internal cable guides that help your ride stay quiet, even over rough trails.
Internal cable routing
We route shift and brake cables through the frame to keep things clean and simple. And it looks great, too.
International Standard Chain-Guide mounts offer easy chain-guide installation and adjustment.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 at the back lets you run wider tyres and a larger chain ring without affecting q-factor and pedalling efficiency.
Threaded bottom bracket
More robust than pressfit, threaded BBs hold up in nasty conditions and make servicing easier.
