The Trek Domane SLR 9 all-road bike in review

Aug 2022 · By

The Trek Domane SLR 9 certainly wins the prize for the most striking paint job. Thanks to its bright Project One colour scheme, you can’t miss it. But can the bike also outshine the competition in terms of all-road performance with its IsoSpeed system and new Shimano DURA-ACE Di2 groupset? We compared it with six of this year’s best all-road bikes to find out.

Highs
  • Best performance in most scenarios

  • Lots of long-distance comfort

  • Very convenient thanks to storage compartment

  • Mounting points for mudguards

Lows
  • Limited seat post adjustability

  • Front cable routing takes a bit of getting used to

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.
