Description
Trek Domane SLR 9 RED AXS Gen 5 Road Bike 2027
Built for cyclists who demand absolute top-tier performance without sacrificing comfort, the Domane SLR 9 RED AXS Gen 5 Road Bike is Trek's ultimate ultra-light endurance road machine. At its core is the highest-level 900 Series OCLV Carbon frame, dropping overall weight to a mere 7.29 kg. Paired with a wireless 2x12 SRAM RED AXS E1 drivetrain, an integrated power meter, and 51 mm deep Bontrager Aeolus RSL 51 carbon wheels, this build delivers instant wireless shifting, deep data tracking, and exceptional aerodynamic efficiency across flat sprints and steep climbs alike.
Pro-Level Precision and Endurance
Combining race-proven efficiency with long-distance compliance, this platform cushions harsh road feedback via an advanced carbon layup and modern cockpit geometry. The Bontrager Pro Riser carbon handlebar and Verse Short Pro saddle relieve key pressure points, ensuring you remain fresh during all-day epics. Supple 35 mm Bontrager Kwaremont RSL tubeless-ready tyres wrapped over lightweight Pirelli TPU inner tubes provide superior traction and low rolling resistance, while generous clearance for up to 40 mm tyres lets you confidently tackle coarse tarmac and gravel connectors.
The Ultimate Turnkey Race Machine
Every detail of this flagship build is optimized for peak power delivery and long-term reliability. A robust threaded SRAM DUB T47 bottom bracket minimizes flex under heavy effort, while the Universal Derailleur Hanger provides a resilient, future-proof drivetrain setup. Featuring precise SRAM Paceline X rotors for dependable stopping control and integrated frame bag and fender mounts for added functionality, the Domane SLR 9 RED AXS offers an unmatched turn-key package for competitive endurance riders seeking unrelenting speed.
