Trek Domane SLR 9 5th Gen road bike Shimano Dura-Ace Di2 12-speed Bontrager Aeolus RSL 51 Mother of Pearl Silver Marble 2027

The 5th-generation Domane SLR 9 represents the pinnacle of the Trek ’s endurance range: a bike designed to go fast for long distances, without ever compromising comfort for performance. Its 900 Series OCLV carbon frame combines lightness with efficiency, whilst its design prioritises a stable and smooth ride, even as the kilometres add up or the road becomes less than perfect.

And to complement this exceptional frame, Trek has clearly pulled out all the stops. The Dura-Ace Di2 2x12 Shimano s groupset delivers that feeling of instant precision characteristic of top-of-the-range groupsets, with fast and perfectly controlled gear changes. The 51mm-high Aeolus RSL 51 OCLV carbon wheels from Bontrager, meanwhile, provide the efficiency needed to turn every pedal stroke into speed.

But the Domane SLR 9’s real strength lies in its ability to perform consistently as the ride goes on. The Endurance geometry, the 20 mm-raised carbon handlebars and the RSL Bontrager seatpost all help to filter out vibrations and maintain a comfortable riding position without making the bike feel clunky. With its 35 mm tyres and up to 40 mm tyre clearance, it can also venture well beyond perfectly smooth tarmac.

The result is a bike that’s just as at home on a fast cyclosportive as it is on a long mountain ride or a day of exploration. A Domane at the pinnacle of its evolution, where comfort, weight and performance are no longer at odds with one another.
