Trek Domane AL 5 Disc 2021 - Road bike

Domane AL 5 Disc is fast, smooth and confident. Trek's best alloy Domane is built with a race-worthy Shimano 105 group set, powerful hydraulic disc brakes and a vibration-absorbing fork and handlebar to keep you feeling fresh on long, competitive rides.

It's right for you if...

You want a comfortable, high-performance alloy road bike built with higher-end components. You're planning to crank out lots of fun, fast miles on the road and even light gravel rail trails.

The tech you get

A 2x11 (22-speed) Shimano 105 drive train has a wide range of gears for riding on any terrain. The lightweight aluminium frame has mudguard mounts and a stable Endurance Geometry for a confident, comfortable ride. Plus, tubeless-ready rims and hydraulic disc brakes for stopping power in any conditions. A carbon fork and IsoZone handlebar absorb fatiguing road vibration.

The final word

Our best aluminium Domane boasts race-worthy parts and a comfortable ride quality that can’t be matched on long rides and rough roads.

Why you'll love it

This versatile bike is fully capable of taking on rough roads, challenging rides, races and even light gravel riding

The unique IsoSpeed Carbon fork, which swoops forward toward the dropouts, absorbs vibrations from the road so your arms won't fatigue as quickly

Setting your wheels up as tubeless reduces the overall weight of your bike and the chance you’ll get a flat

Bigger tyre clearance lets you run wider tyres for more traction and stability on rail 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
