BMC Kaius 01 THREE
Product Details
Meet the BMC Kaius 01 THREE, your ultimate gravel race companion. Engineered for unrelenting speed across all surfaces, Kaius blends lightweight construction, stiffness, compliance, and aerodynamics to deliver an exceptional ride, whether charging across rugged gravel, open deserts, or horizonless backroads.
The premium carbon layup combines ultra-high modulus fibers for maximum power transfer and minimal weight, with high-strength fibers to achieve compliance and robustness. At just 1.785 kg for the module, the frame weighs only 910 g, with a 400 g fork, 160 g seatpost, and 315 g cockpit, giving you the lightweight performance to accelerate and climb with confidence.
Designed specifically for gravel, the Kaius 01 features longer reach and a forward-shifted front wheel to improve stability and traction, paired with a shorter stem for responsive handling. Progressive, race-tuned geometry ensures front-end stability at high speeds while maintaining agile control on loose surfaces.
Kaius comes equipped with BMC’s ICS Carbon Aero Cockpit, offering stealth cable routing, wide adjustability, and world-tour-level performance. The 360 mm top width at the hoods and 420 mm drops with 12.5° flare provide secure control during fast descents. The Aerocore design integrates bottle cages into the frame to optimize aerodynamics, keeping your setup clean and efficient.
Kaius supports 1x or 2x drivetrains, tires up to 44 mm, dropper posts, the MTT Suspension Stem, and top-tube bolt-on bags. Designed for riders who chase speed without compromise, it delivers the ideal balance of stiffness, low weight, and compliance for maximum traction, stability, and climbing efficiency.
Ridden by the fastest gravel cyclists worldwide, including the No Borders Gravel Team, Kaius 01 is built to chase podiums, redefine gravel racing, and push your performance limits on every ride.
