When generation 1 of Kaius launched, the gravel world stood up and took notice. Made with racing as its sole purpose, it defined what gravel speed looked like. Gen 2 raises the bar again. With a 7% aerodynamic gain at 40 km/h, improved stability at speed, and the unmistakable ride feel of our 01 Premium Carbon, the Kaius 01 frameset is engineered for riders who want to build without compromise. 51mm tire clearance, refined compliance, and race-ready geometry give you a platform that stays fast when the course turns rough and the pace stays high. Supplied with frame, fork, and seatpost, the VAR0 frameset features a future-proof Full Mount / UDH interface, giving you total freedom when it comes to drivetrain choice. Finished in raw carbon with a light lacquer and removable decals, it’s ready for custom paint or left as-is for a stripped-back race aesthetic.

Technology

Race-ready geometry

Race day doesn’t care what the surface is doing. That’s why we redesigned the geometry to keep you fast across all of it: sharper up front, calmer at speed, and capable for the wider tires that make modern gravel racing what it is: chaotic, but fast.

Faster with more control

Gravel racing continues to progress – so does our tire clearance. Bigger tires mean more speed and more traction. This gives you the confidence to hit the turns and rough terrain flat-out.

Integrated Cockpit System (ICS)

Minimal, clean, simple: the innovative functionality of the Integrated Cockpit System (ICS) is Swiss design and engineering where it counts. Hidden cables keep the front of your bike looking and feeling fast.

Compliance

Wider tires? Check. Slacker head angle? Check. Optimized carbon layup? Check. Whatever the terrain, you’re getting just the right amount of stiffness and compliance to crush the competition across scorched Spanish deserts or horizonless American gravel.
