Trek Domane SLR 9 5th Gen road bike SRAM Red AXS E1 12v Bontrager Aeolus RSL 51 Mother of Pearl Silver Marble 2027

The 5th-generation Domane SLR 9 Trek is the sort of bike that makes you want to set off for several hours… and then extend your ride a little longer still. It retains everything that has made the Domane renowned for its comfort and stability, but with a level of spec befitting a top-of-the-range bike designed for the most demanding cyclists. Its 900 Series OCLV carbon frame combines lightness, efficiency and vibration damping, keeping you fresh even as the kilometres start to add up.

At the heart of this build, the SRAM Red AXS E1 2x12 drivetrain delivers fast, precise and fully wireless gear changes, with a power metre integrated into the crankset to accurately track your performance. The OCLV carbon Aeolus RSL 51 wheels from Bontrager further enhance the bike’s sporty character with their 51 mm profile, whilst the 35 mm tyres offer an excellent balance between efficiency, comfort and grip.

The Domane SLR 9 doesn’t therefore aim to be merely an ultra-stiff racing bike: it prioritises efficiency that remains consistent even when the road surface deteriorates or the ride gets longer. Its Endurance geometry, raised carbon handlebars and vibration-absorbing seatpost create a comfortable riding position without compromising on speed. With clearance for tyres up to 40 mm wide, mounts for accessories and mudguards, and a claimed weight of just 7.29 kg in size ML, it’s just as at home on a long, sporty ride as it is on a day when the aim is simply to ride far and fast.
