Trek 1120 Disc Gravel Bike 2020
The Trek 1120 Disc Gravel Bike allows you to leave the excuses at home and hit the dirt trails and sandbanks to explore the world. The oversized 29+ tyres provide ultimate grip on soft ground, while the carbon fork provides light and responsive steering.
With a premium aluminium frame, the bike is durable for long-distance touring, while the 1x11-speed groupset brings simplicity and reliability to the mechanics of the bike. Hydraulic disc brakes from SRAM give you all the stopping power you'll ever need on trail, track, lane or road. This probably won't be the lightest bike you've ever ridden, but it's certainly likely to be the most capable.
Features
- 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 harness system makes it easy to secure the 8-litre dry bags of your choice (available separately) in the rear rack and additional bags 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 a fantastic mountain bike – if you're looking to shred, pull off the racks and it's every bit as capable as Trek's award-winning Stache
