Trek Domane AL Disc 4 review: An astounding and affordable all-roader - CyclingTips

Jan 2021 · Dave Rome

Trek's new entry-level road bike combines an endurance fit with sporty handling and a whole bunch of versatility.

Highs
  • Huge tyre clearance, unique geometry is great for the purpose, quite comfortable ride quality, easy to service and upgrade, rides lighter than it feels to pick up, Shimano Tiagra just works, rim width, quality thru-axles.

Lows
  • Basic and heavy frame, making the bike tubeless requires new tyres and a handful of parts, extremely heavy wheels (especially given the bike’s price), handlebar drop shape is too compact.
