The Trek Domane 4.5 disc brings high quality hydraulic brakes to the already very capable 400 series frameset. Upgrades for this year also include a 142x12 rear and 15mm thru axle front standards from high end mountain bikes to deliver extra stiffness under braking allowing you to maximise the impressive power produced by the Shimano RS685 brakeset.

Equipped with Shimano’s Ultegra derailleurs and quality Bontrager finishing components the Trek Domane 4.5 disc is a great all round bike.
