Trek Speed Concept SLR 9 Dura-Ace Di2 TT Bike 2027 Engineered for uncompromised aerodynamic efficiency and effortless speed, the Trek Speed Concept SLR 9 Dura-Ace Di2 TT Bike 2027 represents the pinnacle of time trial and triathlon performance. Constructed from Trek?s top-tier 800 Series OCLV Carbon with Kammtail Virtual Foil tube shapes, this frame cuts through the wind while remaining exceptionally lightweight and responsive. The ride is smoothed by IsoSpeed technology, which absorbs fatigue-inducing road vibrations so you can preserve vital energy for the run. Integrated directly into the frame are dedicated fuel and hydration solutions, including a downtube bottle cage setup and a sleek bento box, ensuring you maintain optimal nutrition without sacrificing aerodynamic drag. Flawless Electronic Precision with Shimano Dura-Ace Di2 At the core of this machine lies Shimano?s flagship Dura-Ace Di2 twelve-speed drivetrain, delivering instantaneous, lightning-fast electronic shifting across a performance-focused 52/36 crankset and an 11-30 cassette. Designed to maximise efficiency on flat out efforts, the dual-control Di2 shifters allow intuitive gear changes directly from the cockpit. A robust Praxis T47 threaded bottom bracket ensures complete power transfer with ultra-smooth rotation, while Shimano Dura-Ace hydraulic disc brakes with 160 mm CL900 CentreLock rotors provide precise, heat-dissipating stopping power in all weather conditions. Race-Ready Carbon Components and Aerodynamic Finishing Kit Rolling on ultralight Bontrager Aeolus RSL 51 OCLV Carbon tubeless-ready wheels, this bike balances stability in crosswinds with maximum speed on open flats. Fitted with supple Bontrager R4 320 tyres, rolling resistance is minimised for optimum inertia. Up front, the fully integrated carbon fork, stem, and basebar system create a streamlined profile, tailored to minimise drag while offering ergonomic adjustability. Completed with a triathlon-specific Bontrager Hilo Pro Carbon saddle, a carbon aero seatpost with adjustable offset, and shock-absorbing Trek gel cork bar tape, this complete setup is crafted to help you shatter personal bests and dominate the field.
