Kaius 01 THREE brings gravel racing to its peak. Equipped with Shimano GRX Di2 and our CG 40 SL carbon wheels, it's built for tough terrains and podium finishes
Engineered by BMC's Impec Lab with advanced premium composite carbon technology, the Kaius 01 THREE is the ultimate gravel-racing machine. Built on a race-optimized geometry, it delivers the ideal balance of stiffness, lightness, and compliance, maximizing traction on loose terrain, front-end stability, and climbing efficiency. Our ICS cable integration and Aerocore design make it one of the fastest bikes ever crafted for gravel racing. Outfitted with Shimano GRX Di2 and CG 40 SL carbon wheels, the Kaius 01 THREE is ready to elevate your speed and performance 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: the fastest on gravel. The geometry features a longer reach to improve stability and increase traction. It's designed for 1x or 2x drivetrains and complies with SRAM Full Mount for UDH dropout or Hangerless Interface derailleurs.
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.
