2025 BMC Kaius 01 One - Acid Yellow/River Blue
BMC- The ultimate gravel racer: speed, stability, performance. With advanced carbon frame, SRAM Red XPLR, ICS Carbon Aero one-piece cockpit and CG 39 SL wheels.
We've turned gravel racing into an obsession, and the Kaius 01 ONE is the result. Born from a dream of ultimate speed, it's a machine designed to crush every race. Engineered by BMC's Impec Lab with cutting-edge composite carbon technology, the Kaius 01 ONE is the pinnacle of gravel performance. With race-optimized geometry, it offers the perfect balance of stiffness, lightness, and compliance, boosting traction on loose terrain, front-end stability, and climbing power. Featuring ICS cable integration and Aerocore design, this carbon gravel bike is built to fly. Outfitted with a full SRAM Red XPLR groupset, power meter, and CG 39 SL Carbon wheelset, it's ready to dominate your next season.
Speed Unbound
The innovative premium carbon layup uses ultra high-module fibres for unmatched stiffness resulting in maximum power transfer and minimal weight. Kaius boasts our Tuned Compliance Concept Race Technology for a comfortable ride on rough surfaces.
Race-ready Gravel Geometry
Kaius was built with one purpose: to be fast on gravel roads. That is why we produced a gravel-specific frame with a longer reach shifting the front wheel forward to improve stability and increase traction on loose surfaces.
ICS Carbon Aero Cockpit
The ICS Carbon Aero Cockpit, with its progressive and aerodynamic shape, is the perfect match for this bike. Featuring a narrow top width, allowing an efficient aero position with a greater width at the drops providing incredible control at high speed.
Aerocore Design
Kaius comes in at the highest level of functional integration with our Aerocore design. This evolved solution integrates the bottle cages into the frame to optimize aerodynamic performance.
