1120 | Trek Bikes (CA)

You live for freedom, value self reliance, and want a ride for bikepacking and off-road touring in places other bikes simply can't take you. 1120 is for the crazy among us and those who feel most at home under the stars. If filling out the last uncharted parts of the map is your thing, 1120 is the thing to do it on.

Aluminum frame with adjustable rear horizontal sliding dropout, a carbon fork, our proprietary rack system and included bag holsters that secure and protect 8L dry bags of your choice, a wide-range 1x12 Shimano drivetrain, Shimano 4-piston hydraulic disc brakes for superior stopping power, 29+ tires, and a Bontrager Line dropper post that makes it easy to mount, dismount, and descend while loaded.

The bike you get if you're after real adventures. Every part of 1120 is made for better bikepacking and built to take on the burliest trails you can find. Included racks, trail-specific spec, and 29+ wheels make 1120 the perfect shred sled for epic exploration.

This bike expands boundaries and lets you escape, and it's equipped with the right spec so you can just pack it and go
The included rack and durable harness system makes 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 awesome 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 convert to singlespeed if your derailleur busts out in the wild

Hydraulic disc brakes offer the absolute strongest stopping power in all conditions, including wet and muddy.

Bontrager TLR (Tubeless Ready) Road is the first fully integrated tubeless system for the road. No tubes mean there’s no pinch flats, allowing you to run lower tire pressure. With lower tire pressure you can increase traction, control. and comfort, reduce fatigue on you. Best of all, the tire sealant seals up punctures as soon as they happen!

Lightweight fork with carbon fibre legs soaks up hand-numbing road vibration.

A 15mm front thru axle makes steering more precise for more control, and the quick-release feature makes wheel removal easy.

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.

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.

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.

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.

How do you fit a 29" tyre without elongating the wheelbase? Elevate the drive-side chainstay up and out of the way.

Stache is optimized for a single chainring. No front derailleur means a tighter wheelbase for a lively ride.

Bike and frame weights are based off pre-production painted frames at time of publication. Weights may vary in final production.

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.
