Trek Speed Concept SLR 9 Sram Red AXS E1 12-speed Triathlon/Time Trial Bike Bontrager Aeolus RSL 51 Party Purple

The Trek Speed Concept SLR 9 is a high-end triathlon and time trial bike, designed for cyclists seeking speed, aerodynamics and efficiency over long distances.

Its 800-series OCLV carbon frame, featuring Kammtail Virtual Foil aerodynamic profiles, is designed to reduce air resistance and optimise performance at high speeds. IsoSpeed technology, integrated into the top tube, helps absorb road vibrations to maintain comfort during long races.

Its SRAM RED AXS E1 2x12-speed electronic drivetrain, fitted with an integrated power metre, enables precise gear changes and power monitoring. Bontrager ’s Aeolus RSL 51 OCLV carbon wheels combine lightness and aerodynamics to support acceleration and maintain high speeds. The mid-height, integrated Speed Concept cockpit makes it easy to adjust your position to strike a balance between aerodynamics, comfort and efficiency. The integrated storage system for hydration and nutrition allows you to tackle long distances whilst minimising the need to change position.

With its Party Purple finish, RED hydraulic disc brakes from SRAM and 700 x 25 mm R4 320 tyres from Bontrager, the Trek Speed Concept SLR 9 is designed for demanding triathletes and time trial specialists.
