Triathlon/Time Trial Bike Trek, Speed Concept SLR 9 Shimano, Dura-Ace 12-speed Bontrager, Aeolus RSL 51 Serpentine

The Speed Concept SLR 9 Trek is a high-end triathlon and time trial bike, designed to maximise speed through its aerodynamic design and advanced component integration.

Its 800-series OCLV carbon frame, featuring Kammtail Virtual Foil (KVF) profiles, is designed to reduce air resistance and optimise performance on time trial courses. IsoSpeed technology helps absorb road vibrations to improve comfort over long distances and conserve the rider’s energy.

Its Shimano Dura-Ace Di2 12-speed electronic drivetrain offers precise and rapid gear changes, tailored to the demands of competition. The Bontrager Aeolus RSL 51 carbon wheels, with their 51 mm rims compatible with Tubeless Ready, combine aerodynamics and efficiency to maintain high speed. The Speed Concept integrated handlebar set allows for fine-tuning of the aerodynamic position thanks to several height and size-specific adjustment options. The integrated hydration and storage systems facilitate access to refreshments whilst minimising changes in position during the ride.

With its Serpentine finish, Bontrager Hilo Pro Carbon saddle and Shimano Dura-Ace hydraulic disc brakes, this bike is designed for triathletes and time trial specialists seeking peak performance.
