BMC Kaius 01 THREE Gravel Bike

Kaius is a premium carbon gravel bike built to be your elite race companion for all terrains. The unprecedented carbon layup and gravel-specific geometry ensure the perfect balance of stiffness, lightweight, and compliance for optimal traction on loose surfaces, front-end stability, and unmatched climbing prowess. Harnessing the precision and performance of our renowned leading road technologies, Kaius is a race machine tuned to the gravel wavelength with the engineered Kaius fork, our signature ICS2 stem and conventional bar, TCC Race compliance, compatibility with 1x and 2x drivetrains and up to 44 mm of tire clearance.

Speed Unbound
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 and targeted reinforcements protect your frame against the demands of gravel racing.

Race-ready Gravel Geometry
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. With the shorter stem providing responsive handling, Kaius sports a progressive and race-tuned geometry for evolving riding styles.

Integrated Cockpit System (ICS)
ICS2, with significant weight savings, high stiffness, clean aesthetics and integrated device mounts for the most popular devices.

Aerocore Design
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.

Lightweight
Being a race bike, Kaius is not only stiff and comfortable but also lightweight. With a frame weighing only 910g, the fork 400g, a seat post at 160g, and the cockpit clocking in at 315g, we produced a module that is going to make you fly up the hills at a lightweight 1.785 kg.

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