Bmc:
the kaius 01 three is built for fast gravel racing, combining bmc’s 01 premium carbon construction with race-optimised geometry and the integration expected from the kaius platform. Engineered by bmc’s impec lab, it is designed to balance stiffness, low weight and compliance, giving riders efficient power transfer, climbing performance and stability when the surface becomes loose or unpredictable.
Its gravel-specific geometry uses a longer reach to improve front-end stability and traction, helping the bike stay composed across fast gravel sectors, rough tracks and technical race conditions. Tuned compliance concept race technology helps smooth out rougher surfaces without taking away from the direct response needed for high-intensity efforts, while ics cable integration and aerocore design keep the frame clean and aerodynamically focused.
Finished with Shimano grx Di2 2 x 12-speed shifting, a 4iiii precision gen3+ non-drive-side power meter, bmc rsm 01 integrated stem and cg 40 sl carbon tubeless-ready wheels, the kaius 01 three delivers a race-ready gravel build with the control, gearing range and speed needed for tough terrain and long competitive efforts.
