It's right for you if...
You live for freedom, value self reliance and want to build up an amazing bike-packing and off-road touring bike that'll take you to places that other bikes simply can't.
The tech you get
Aluminium frame with adjustable rear horizontal sliding dropouts, a carbon fork, mounts for our proprietary rack system, and an internal derailleur and dropper post routing. Plus, a carbon fork and an FSA headset. Made for Boost148 29er wheels and 12 mm thru axles.
The final word
The frame you get if you want to build up a bike for big adventures. Every part of 1120 is made for better bike-packing and built to take on the burliest trails you can find.
favorite_borderWhy you'll love it
- This boundary-expanding bike is ready to be spec’d for however you love to adventure
- Our 1120 rack and durable harness system (sold separately) make it easy to secure 8L bags in the rear rack and additional gear up front for the best packing balance
- So many mounting features let you set up your ideal expedition ride as you see fit
- It's also an outstanding mountain bike – if you're looking to shred, just pull off the racks
- The horizontal sliding dropout lets you dial in your geometry and easily converts to singlespeed if your derailleur busts out in the wild
A 15mm front through axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.
Dropper post internal routing
Not ready for an internally routed dropper post now, but want to keep your options open? Select frames are equipped with the proper entry and exit points to accommodate internal routing for a Stealth seat post.
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.
How do you fit a 29" tyre without elongating the wheelbase? Elevate the drive-side chainstay up and out of the way.
Built for 1X
Stache is optimised for a single chain ring. No front derailleur means a tighter wheelbase for a lively ride.
29+ is a wider 3" tyre that grips relentlessly while floating over terrain. Yet it delivers all the 29er benefits that you know and love, like greater momentum and improved rollover.
