The ultimate blank canvas for building your fastest gravel race bike.
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.
