Trek Domane AL 5 Disc Road Bike 2022
Marrying a strong alloy frame, carbon fork and reliable performance components, the Trek Domane AL 5 Disc Road Bike is fast, light and comfortable. IsoSpeed technology is incorporated into the fork and helps to smooth out vibrations coming up from the road, preventing excess fatigue. Endurance Geometry is a little less aggressive than race geometry, allowing you to ride all day without any compromises on speed. The tubing itself has been designed to be more aerodynamic than its predecessor and, alongside hidden cable routing, minimises drag. There's clearance for wider tyres - up to 38c - so you can set up the bike for mixed terrains and venture further off the tarmac, while the mudguard mounts allow you to get ready for all weather conditions.
The Shimano 105 11-speed groupset balances reliability and performance well, with shifting incredibly smooth and precise up and down the cassette. Hydraulic discs take care of braking, no matter the conditions. Compatible with the DuoTrap S sensor (purchased separately), you can collect speed and cadence data from your rides and transfer it to a compatible smartphone for analysis. Rolling on Bontrager tubeless-ready wheels, make the conversion from a tube-type setup and benefit from faster rolling, more comfort and the elimination of potential pinch flats.
Highlights
- Trek 100 Series Alpha Aluminium frame with 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 105 11-speed compact drivetrain
- Shimano 105 hydraulic disc brakes
