Trek Domane AL 2 Disc Road Bike 2021
Bringing together a responsive, stable ride feel with reliable components, the Trek Domane AL 2 Disc Road Bike is a great entry point into the world of road cycling. Endurance Geometry focuses on comfort without compromising performance. The bike is designed to suit long hours in the saddle, to get the miles in without any aches and pains, and the carbon fork incorporates IsoSpeed bump-smoothing technology, slowing the onset of fatigue caused by harsh road surfaces.
There's space for wide 38mm tyres and mounts for mudguards, so you can set the Domane up for longer adventures in all conditions on mixed terrains. Claris and Sora may be Shimano's more entry-level components, however, they're still reliable - shifting is smooth and braking powerful even in the wet. Robust tubeless-ready Bontrager wheels are a solid choice, built to last and roll fast, and they're ready to be set up tubeless if you prefer.
- Trek 100 Series Alpha Aluminium frame and hidden cables
- The unique IsoSpeed Carbon fork, which swoops forward toward the dropouts, absorbs vibrations from the road so your arms won't fatigue as quickly
- Endurance Geometry
- Setting your wheels up as tubeless reduces the overall weight of your bike and the chance you’ll get a flat
- Bigger tyre clearance (up to 38c) lets you run wider tyres for more traction and stability on trails and other light gravel roads
- DuoTrap S compatibility makes it easy to wirelessly track your rides, so you can set goals and watch yourself reach them
- Shimano Claris 8-speed compact drivetrain
- Tektro C550 mechanical disc brakes
