Trek 920 Disc Adventure Bike 2020
The Trek 920 disc is built for gravel bike adventures. This bike is aimed at touring and bike-packing, giving you the freedom to go anywhere. It combines a lightweight 100 Series Alpha Aluminium frame with an alloy fork and offers a stable, yet still a fast and fun ride, on roads, trails and gravel - pretty much anything you point it at.
The SRAM drivetrain provides you with a wide range of gears to get you up steep hills, even when fully loaded, and hydraulic discs bring the power you need to stop fast on all terrain and in any conditions. Bontrager's Duster Elite tubeless-ready 29" wheels are incredibly strong and sized to roll across any surface.
The incredibly sturdy front and rear racks that are included allow you to carry 25kg and 11.8kg of cargo, back and front respectively, and there are numerous mounts for mudguards, lights, navigation and plenty of water bottles.
- If you want to ride around the world, this is the right bike for you
- Extra water bottle mounts, including one on the underside of the down tube
- It comes with burly front and rear racks that can handle more gear than you'll ever want to carry (25 kg at the back, 11.8 kg at the front)
- Balanced geometry is ultra-stable even when fully loaded
- SRAM mountain 2x10-speed drivetrain
- SRAM hydraulic disc brakes
- Tubeless-ready rims
- Bontrager Blendr technology lets you clip gear directly to the stem
- 15mm front quick-release thru-axle for more precise steering and easy wheel removal
