Description
1120 frameset is a bikepacker's dream. The rugged all-terrain frame is made for 29+ tires, has loads of mounts for gear, and can run a dropper post. Build it up exactly as you want, and explore the most extreme backcountry destinations in the farthest reaches of the world.
- 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 on 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 awesome mountain bike — if you're looking to tear up some singletrack, just pull off the racks
- The horizontal sliding dropout lets you dial in your geometry and easily convert to singlespeed if your derailleur busts out in the wild

A better way to produce aluminum
Starting in 2024, we began removing high-emission aluminum from our manufacturing and replacing it with low-emission aluminum made with renewable energy. By October 2025, nearly every alloy bike we make - this one included - had made the switch, driving a major drop in our footprint.
