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 Domane is a tremendously smooth bike thanks to Trek’s IsoSpeed rear damping system and high volume, 32mm tubeless tyres
The new Domane is everything great about the old bike, plus lighter and quicker.

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.
Best performance in most scenarios
Lots of long-distance comfort
Very convenient thanks to storage compartment
Mounting points for mudguards
Limited seat post adjustability
Front cable routing takes a bit of getting used to

In these days of ever-increasing bike prices, Trek’s entry-level Domane is still refreshingly affordable
Excellent component specification
The handlebar can transmit vibration at high tyre pressures on rough stuff

Major changes include elimination of the seat mast, front IsoSpeed and adjustment on rear IsoSpeed.

Smooth-riding endurance bike with loads of tyre space and masses of versatility
Space for big tyres
Not especially light
Dave RomeJan 2021
Trek's new entry-level road bike combines an endurance fit with sporty handling and a whole bunch of versatility.
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.
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.
