Gravel Racing, Redefined. The Kaius 01 is the result of BMC’s obsession with gravel speed. Engineered in the Impec Lab with cutting-edge carbon technology, it’s purpose-built for competitive gravel racing. Its race-optimized geometry delivers the ideal mix of stiffness, low weight, and compliance - enhancing traction, stability, and climbing efficiency across demanding terrain. With the RSM01 stem featuring ICS cable integration and our new aluminum HB-D4-03 handlebar, our Aerocore design, this bike cuts through the wind and charges ahead. Equipped with top-tier components like the newest SRAM Rival AXS XPLR, and CG 40 carbon wheels, the Kaius 01 is ready to chase podiums and push boundaries on every ride.

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.

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.

The aesthetic simplicity and innovative functionality of the Integrated Cockpit is the epitome of Swiss engineering and design. ICS keeps shifter wires and brake lines in their place: out of sight.

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.
