The Trek Domane ALR 4 Road Bike 2017 is designed to offer comfort, performance and value; truly a holy trinity when it comes to looking for a new bike. With Trek's IsoSpeed Decoupler technology offering comfort and stability over rough roads, this is the perfect all-round choice for the value-minded rider.

Trek Domane ALR 4 Road Bike 2017

The Trek Domane ALR 4 Road Bike 2017 has it all. Blistering speed, incredibly race comfort and stability, and fantastic value. The frame is constructed from Trek's 200 Series Alpha Aluminium with sophisticated tube shapes for maximum strength and a low weight. This frame is coupled with the Domane Carbon fork for strength, durability and comfort.

At the core of the Domane ALR's frameset's comfort is the IsoSpeed decoupler. The decoupler is designed to allow the seat tube to rotate independently fro the top tube, increasing vertical compliance to twice that of the nearest competitor without compromising pedalling efficiency. The result is a more comfortable ride, especially over rougher road surfaces.

Trek have also paid particular attention to the finishing kit with a selection of superb kit that allows the Domane ALR 4 to punch above its price tag. Gearing is provided by Shimano's 10-speed Tiagra system. The compact crankset and 11-32 cassette provide you with a wide range of gears that are more than capable of powering over the toughest terrain.

Tektro's T731 brakes combine with Bontrager's Tubeless Ready wheels for superb stopping power in both the wet and the dry. Bontrager also provides the tyres in the form of their R1 Hard-Case Lite model. At 28 millimetres wide, these tyres are perfect for long rides when comfort becomes of the utmost importance.
