Carbon endurance road bike Trek Domane SLR 9 AXS for training: SRAM RED AXS, power meter, 7.29 kg

Trek Domane SLR 9 AXS: top-end wireless that measures your watts

The Trek Domane SLR 9 AXS Gen 5 combines OCLV Series 900 carbon with the wireless SRAM RED AXS E1 2x12 drivetrain with power meter, on Aeolus RSL 51 wheels. It weighs 7.29 kg in size ML, without giving up the 35 mm tyres that give the Domane family its comfort. The Mother of Pearl/Silver Marble colourway gives it a pearly white shot through with marbled silver highlights.

Technical specifications

Who is it for?

For the sportive rider preparing for a specific goal, following a training plan and wanting reliable power data on every ride. It will also suit the rider discovering zone-based training who prefers a power meter included from the outset to a separate purchase.

The LVR workshop view

OCLV carbon, Trek's signature. Trek has made its carbon frames using the OCLV process since 1992: heat and pressure compact the fibre layers and eliminate air pockets. The number that follows indicates the degree of optimisation, and 900 is the highest. Moulded in 3D in rigid tooling, with few overlaps, the SLR 9 AXS frame weighs approx. 835 g unpainted in ML, some 220 g less than an SL, and is up to 20 % stronger than OCLV 800. The RED groupset and RSL rims do the rest to reach 7.29 kg.

For training, the combination makes sense: power measurement helps you ride at the right intensities, and the slightly upright position lets you hold long blocks at threshold. On the short climbs around Béziers, accelerations are lively thanks to the stiff frame and light wheels.

The power meter housed in the RED chainset is this version's main asset, with no parts to add. The 48/35 and 10-36 cassette also offer more flexibility on climbs than the 50/34 and 11-34 of the Shimano SLR 9. Before handover, we pair the shifters and power meter with your computer.

Which Domane should you choose?

Our take: the SLR 9 AXS weighs 50 g less than the Shimano SLR 9 (7.29 against 7.34 kg) and adds power measurement. To save another 660 g, you have to accept the 1x13 and 28 mm tyres of the SLR 9 AXS 1x.
