If filling out the last uncharted parts of the map is your thing, 1120 is the thing to do it on.
The tech you get

Comes with a headset and front and rear thru-axle skewers.
The final word
Every part of 1120 Frameset is designed for better bikepacking and built to take on the burliest trails you can find. Spec it how you like and build up your ideal rig for epic adventures.

Features
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.
Stranglehold dropout
Horizontal sliding dropout with redundant securing mechanisms allows for no-slip singlespeed or geared options and provides the ability to dial in the geometry to match each rider’s style.
Mid-stay
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 optimized for a single chainring. No front derailleur means a tighter wheelbase for a lively ride.
Boost148/110
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 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.
