The Trek Domane AL 5 Gen 4 is built for riders who want the speed of a road bike with the comfort to tackle longer distances. Whether you're training for sportives, joining weekend club rides or commuting during the week, it combines dependable performance with everyday practicality in a well-rounded package.

The frame is constructed from Trek's lightweight 100 Series Alpha Aluminium and features an endurance-focused geometry that places you in a comfortable, efficient riding position for long hours in the saddle. Internal cable routing gives the bike a clean, premium appearance, while a tapered head tube improves front-end stiffness and steering precision. Trek has also transitioned this frame to lower-emission aluminium produced using renewable energy, helping reduce the environmental impact of manufacture.

A full carbon Domane AL fork keeps weight down while helping absorb vibration from rough roads, improving comfort without sacrificing responsive handling. Internal brake routing maintains the bike's clean lines, while integrated mudguard mounts add practicality for year-round riding.

The Shimano 105 R7100 2x12-speed drivetrain delivers the crisp, dependable shifting that has made 105 a favourite among performance-focused riders. Borrowing technology from Shimano's Ultegra and Dura-Ace groupsets, it combines a compact 50/34T chainset with an 11-34T cassette to provide a broad range of gears for steep climbs, fast descents and everything in between.

Shimano 105 hydraulic disc brakes offer powerful, predictable braking in all weather conditions. Excellent modulation and consistent stopping performance inspire confidence whether you're descending quickly or riding through wet winter roads.

Bontrager alloy wheels are paired with Bontrager Kwaremont Comp 700x32mm tyres featuring Hard-Case Lite puncture protection. The wider tyres improve grip and comfort on imperfect road surfaces, while generous tyre clearance also allows larger tyres to be fitted for light gravel riding and mixed-surface adventures.

Practical mounting points for mudguards, a rear rack, top tube bag and multiple bottle cages make it easy to tailor the Domane AL 5 for commuting, touring or long-distance riding. The Universal Derailleur Hanger (UDH) also simplifies sourcing replacement hangers should the need arise.

The updated Bontrager handlebar features a subtle flare between the hoods and drops for greater comfort and control, while the Blendr-compatible stem makes it easy to mount compatible lights and cycling computers neatly.

Built on Trek's racing heritage but designed with versatility in mind, the Domane AL 5 Gen 4 is a road bike that rewards riders as their ambitions grow. Its blend of comfort, reliable Shimano 105 performance and everyday practicality makes it an excellent choice for riders looking to cover more miles with confidence.
