The Perfect Gravel Machine

Kaius crushes the competition with the perfect combination of weight, stiffness, compliance, and aerodynamics. Teaming unmatched climbing capabilities with sprint-winning power transfer and the requisite strength for peace of mind against stone strikes, Kaius opens the full spectrum of what is possible on every surface you encounter.

The unprecedented premium carbon layup uses high-module fibres to push weight to a minimum and power transfer to a max while high-strength fibers are used to achieve compliance and robustness.

Race-Ready Gravel Geometry

Tune your ride to the gravel wavelength to harness the precision and performance of our leading road technologies whilst ensuring front-end stability at speed and high traction on loose 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. With the shorter stem providing responsive handling, Kaius sports a progressive and race-tuned geometry for ever-evolving riding styles.

Integrated Functionality

Adding proven performance and welcome usability, Kaius uses our lightweight ICS cockpit systems where integrated stealth cable routing and mounts mesh with wide adjustability and WorldTour performance in an advanced one-piece cockpit system.

Our signature ICS Carbon Aero Cockpit comes into play on Kaius 01 ONE to match the performance of our race machines with a reduced frontal section. The 360 mm top width at the hoods allows for an efficient aerodynamic position, while the 12,5° flare and the 420 mm width at the drops provide great control at high speeds.

Arriving at the highest level of integrated functionality, Kaius features our Aerocore design, an evolved solution that integrates the bottle cages into the frame to optimize aerodynamic performance.

Lightweight and Versatile

Being a race bike, Kaius is not only stiff and compliant, but also lightweight. The module clocks in at a mere 1.785 kg, with a frame weighing only 910 g, the fork 400 g, the seat post 160 g, and the cockpit 315 g. This gravel machine is going to make you fly up those hills at the speed of light.

Kaius comes with all you would expect from a high-end gravel race bike. Versatile by design, it can fit 1x and 2x drivetrains, tires up to 44 mm, a dropper post, our new MTT Suspension Stem, and top tube bolt-on bags.

No Borders Gravel Team

The BMC Kaius is young but already iconic, ridden by the fastest gravel cyclists globally and by athletes who seek to maximize their careers while juggling full-time jobs. The No Borders Gravel Team epitomizes a family of hardworking individuals who transform into highly competitive forces when faced with the start and finish lines at the end of a dirt road. Their competitive edge lies in the Kaius. "It's like racing BMC’s Speedmachine but without compromising on comfort. It's a true machine." – Lisa Wörner
