Trek Domane AL 3 Road Bike 2020
The Trek Domane AL 3 is an accessible option that's perfect for riders taking their first pedal strokes on a road bike. The Shimano Sora groupset has a wide range of gears to make climbing hills easier, all controlled through the same levers that operate the brakes.
The 28mm thick Bontrager tyres provide an extra volume of air for a more comfortable ride, which is further enhanced by the IsoSpeed carbon fork which absorbs vibrations to the front end. Endurance Geometry means you can ride for longer in total comfort.
- The Trek Domane AL 3 is a great-looking bike for a great price, and it's a super foundation for a happy future of road riding
- A lightweight frame and quality parts make it a totally appropriate platform for fast group rides
- The stable Endurance Geometry is comfortable over long distances, but this is still a quick racing bike
- The unique IsoSpeed Carbon fork, which swoops forward toward the dropouts, absorbs vibrations from the road so your arms won't fatigue as quickly
- DuoTrap S compatibility makes it easy to wirelessly track your rides, so you can set goals and watch yourself reach them
