Trek 1120 Review

A bikepacker’s fantasy, 1120. A touring bike with limitless off-road potential is made possible with a tough all-terrain frame, 29+ tyres, a built-in rack system, and mountain-ready components like a 1x drivetrain. This bike is made to travel to the most remote backcountry locations in the globe, but it’s also perfect for quick overnight bikepacking excursions and sub-24s.

You should consider it if you respect independence, value freedom, and want a vehicle for off-road travel and bikepacking in areas where other bikes can’t go. Trek 1120 is intended for the eccentric and nocturnal personalities among us. Trek 1120 is the vessel to use if filling in the final unexplored areas of the map is your thing.

A wide-range 1×12 Shimano drivetrain, a carbon fork, our custom rack system, included bag holsters that secure and protect 8L dry bags of your choice, Shimano 4-piston hydraulic disc brakes for superior stopping power, 29+ tyres, and a Bontrager Line dropper post that makes it simple to mount, dismount, and descend while loaded are all included in the technology you get.

Aluminum Alpha Platinum Frame

Trek 1120 frame is built of sturdy aluminum and carbon. Aluminum Alpha Platinum is used in its construction. The bike’s frame was created using Trek’s ground-breaking Stache platform.

The Trek 1120 frame is quite tough because it was designed to handle any terrain. It does weigh a little bit more than some Trek mountain bikes that are identical to it because of how tough the frame is.


The Trek 1120 offers every gear you should require for lengthy rides over challenging terrain. The simple and efficient 1x drivetrain has a wide range. For both mountain trails and dirt roads, the gearing performs admirably. This bike may be used for everything from flat terrain to off-road travel in harsh conditions.

There are 11 gears on the Trek 1120. The high-quality gearing mechanism on this bike allows it to be used for both on-trail and off-trail adventures.

Shimano is the manufacturer of all the shifters and gears used in the drivetrain. This mechanism makes shifting gears simple and ensures that the vehicle stays in the gear you intend it to be in.


Large 29+ wheels are on the Trek 1120. These wheels have excellent grip and roll quickly. The huge wheels assist in absorbing much of the shock from below on uneven ground. The wheels are over three inches wide, which provides excellent ground contact and keeps the bike stable under all conditions. With the rims on these wheels, tubeless tyres can be used to lower tyre pressure and avoid flats.

Trek 1120 wheels have excellent stability, durability, and traction. The 28-spoke wheels are reasonably sturdy.

Carbon Fork & Suspension

The Trek 1120 Adventure HCM Carbon Fork is the name of the suspension-corrected fork. It consists of a steerer tube constructed of bonded alloy with a carbon fork and crown. The fork has triple accessory bosses on either side, 110mm BOOST spacing, and rack mounts just above the dropout.

The major purpose of the Trek 1120 is to be used for bikepacking journeys, and this suspension system is very good in protecting the rider from the elements. The user won’t experience any jolts as the bike smoothly glides over obstacles like pebbles and sticks.

Newfangled Racks

These specialized aluminum racks offer a very sturdy surface for strapping various types of equipment. By providing creative ways to attach gear and drybags to the bike, they also do away with the necessity for a typical seat pack and handlebar roll. In general, they allow the bike to carry more goods than with a typical bikepacking arrangement.

Oh! What a feeling factors

This bike breaks down barriers and allows you to flee, and it has the necessary specifications so you can easily pack it up and go.

For the greatest packing balance, it is simple to secure 8L bags in the rear rack and additional gear up front using the sturdy harness system and integrated rack.

You can configure your ultimate excursion ride however you see fit thanks to so many mounting options.

It also makes a great mountain bike; simply remove the racks if you want to shred.

If your derailleur breaks in the middle of nowhere, you can easily switch to singlespeed thanks to the horizontal sliding dropout.
