Musings
  • An ultra light weight 28.5lb electric road bike with endurance comfort geometry and iso speed vibration dampening seat post interface. The first ebike to feature Trek's OCLV carbon fiber. Available in five colors and seven frame sizes.

  • This particular build uses top of the line SRAM components with a 1x12 drivetrain, flared drop bar, and 40c wide gravel tires. Alternative builds offer narrower road tires and a 2x12 Shimano drivetrain. SRAM Red electronic shifting and 160mm hydraulic disc brakes.

  • Hidden fender mounts add utility, integrated top top tube display panel works well and is easy to read, optional smartphone app provides motor tuning settings, optional range extending 160wh bottle shaped battery pack provides 40% more range and off-bike charging.

  • Excellent control pad button placement on left and right hood. Includes 4 amp fast charger despite having a lower capacity 360wh battery. Main battery not removable for charging and storage. Seat post is a proprietary shape so upgrade options are limited.

The Trek Domane SLR 9 all-road bike in review

Tobias HörschAug 2022

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.

Pros
  • Best performance in most scenarios

  • Lots of long-distance comfort

  • Very convenient thanks to storage compartment

  • Mounting points for mudguards

Cons
  • 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

Dave RomeJan 2021

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

Pros
  • 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.

Cons
  • 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.
