BMC Kaius 01 – aero gravel bike built for race-level speed

BMC Kaius 01 is designed with one clear goal – to go faster on gravel. It brings road bike aerodynamics to off-road terrain while maintaining low weight, stiffness, and control. On long, fast rides, it allows you to hold an efficient position and consistent pace, even when the surface becomes more demanding.

Key features:

• Aero-optimized frame: solutions derived from the Teammachine R reduce drag and help maintain higher speeds on long gravel sections
• Halo fork: wide fork design channels airflow away from the wheel and allows clearance for wider tires, improving stability
• Increased stiffness (+3%): more efficient power transfer enables faster acceleration and sustained high-speed riding
• Lightweight construction: low weight is maintained despite aerodynamic and stiffness improvements
• Tuned Compliance Concept: frame absorbs vibrations, enhancing comfort and control on rough terrain
• AS10 aero seatpost: lightweight and aerodynamic, while helping to absorb small road vibrations
• AeroCore downtube: specially shaped tube optimizes airflow even when bottles are mounted
• Aero head tube + ICS Carbon Aero cockpit: integrated front-end solution reduces drag and improves handling precision
• Stable race geometry: supports an efficient riding position for long distances and high-speed control
• Grip = speed: better traction improves power transfer and allows faster riding on challenging surfaces
• Race-focused design: optimized for high average speeds (30–35+ km/h) and long, intense gravel races
