Carbon endurance road bike Trek Domane SLR 9 for long distances: Dura-Ace Di2, Aeolus RSL 51 wheels, 7.34 kg

Trek Domane SLR 9: top of the range for very long distances

The Trek Domane SLR 9 Gen 5 brings together OCLV Series 900 carbon, the electronic Shimano Dura-Ace Di2 2x12 drivetrain and Bontrager Aeolus RSL 51 wheels, for 7.34 kg in size ML. Its endurance geometry and 35 mm tyres are aimed at six- or seven-hour days, where staying fresh matters as much as speed. This Mother of Pearl/Silver Marble colourway combines a pearly white with marble-like silver veins that change with the light.

Technical specifications

Who is it for?

For the long-distance rider who lines up audaxes, long sportive routes or day rides into the hinterland. It is for the rider who wants the best equipment without adopting a race position: the 20 mm riser bar relieves your neck and back as the hours add up.

The LVR workshop view

OCLV carbon, Trek's signature. The OCLV acronym refers to Trek's in-house method, applied since 1992: the carbon sheets are pressed and cured so as to drive out the air trapped between them. The Series 900 of the SLR 9 is the culmination of this process. Thanks to rigid 3D moulding and reduced fibre overlaps, the frame weighs approx. 835 g unpainted in ML, about 220 g less than a Domane SL, while being up to 20 % stronger than the previous OCLV 800. The rest of the gap with an SLR 7 comes from the components: Aeolus RSL wheels and Dura-Ace groupset.

For long distances, though, it is the tyres that provide the comfort. The 35 mm Kwaremont RSL tyres can be set up tubeless and tolerate moderate pressure, which smooths out the coarse surfaces of the Minervois. The frame also takes bags thanks to its integrated mounts: a real asset for an audax or a lightly loaded self-supported weekend.

Dura-Ace R9250 Di2 keeps a 50/34 and an 11-34 cassette, classic sportive gearing, with crisp shifts even under load. At every service, our workshop updates the Di2 system; the threaded T47 bottom bracket makes bearing replacement simple.

Which Domane should you choose?

Our take: with an identical frame, the SLR 9 weighs 320 g less than the SLR 7 (7.34 against 7.66 kg) thanks to Dura-Ace and RSL wheels. The SLR 9 AXS saves only 50 g more, but adds a power meter and a 48/35 that is easier on climbs.
