Carbon endurance road bike Trek Domane SLR 9 AXS for audaxes: RED AXS, power meter, 35 mm tyres, 7.29 kg

Trek Domane SLR 9 AXS: pacing your effort over long distances

Designed to last without wearing you out, the Trek Domane SLR 9 AXS Gen 5 weighs 7.29 kg in size ML with its OCLV Series 900 frame, Aeolus RSL 51 wheels and SRAM RED AXS E1 2x12 groupset. The power meter built into the chainset becomes an invaluable guide when the ride goes beyond 200 km. Its Navy Smoke/Trek White livery combines a navy blue with smoky highlights and touches of white.

Technical specifications

Who is it for?

For the sporty randonneur and the audax enthusiast who want to keep a steady pace from the first kilometre to the last. The displayed power stops you setting off too fast, the 35 mm tyres limit fatigue, and the integrated mounts take the bags for a self-supported ride.

The LVR workshop view

OCLV carbon, Trek's signature. A carbon frame is weakened where air remains trapped between the layers; the OCLV process, launched by Trek in 1992, compacts the fibres under pressure and heat to prevent this. Series 900 takes the logic as far as it goes, with rigid 3D moulding and fewer overlaps. For you, that means a Domane frame of approx. 835 g, about 220 g less than in OCLV 500, and up to 20 % tougher than the previous 800, which is reassuring over the long term. If this SLR 9 AXS remains lighter than an SLR 7 AXS, it is thanks to the RSL wheels and RED.

Over several hours, the wireless drivetrain has another advantage: no cable stretching or adjustment shifting, and shifters you can operate even in winter gloves. The AXS batteries can be swapped in a few seconds; a spare battery slipped into your bag is enough for peace of mind on a very long day.

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.
