The BMC Kaius 01 One is BMC's top-tier gravel race bike — built for competition, not exploration. Where the URS handles long days in the wilderness, the Kaius exists for one purpose: finishing gravel races faster. This is the second generation of the Kaius 01, redesigned from geometry to cockpit based on what the first version revealed about what a gravel racer actually needs. It tips the scales at 7.1 kilograms in size 54 with all accessories, carries a full SRAM Red XPLR AXS build, and arrives ready to race.

The Gen 2 frame is built from BMC's 01 Premium Carbon — the same layup used in the Teammachine road platform — shaped around an Aerocore Design with tube profiles tuned specifically for gravel racing's demands. The geometry was reworked for this generation: sharper and more responsive up front, calmer at speed, and capable of running tires up to 52mm on the rear 12x142mm thru-axle. A Universal Derailleur Hanger simplifies wheel and derailleur changes in the field. BMC's Tuned Compliance Concept (TCC) governs how the frame and fork flex — calibrated to absorb sustained vibration without bleeding power on the rough stuff. All cabling routes internally through the frame via ICS Technology, and BMC reports a 7% aerodynamic improvement over the first-generation Kaius at 40 km/h. Five cargo mounts are integrated into the frame without disrupting its silhouette: two bottle cage positions with AeroCore integrated cages, a bottom bracket mount under the downtube, and dual top tube positions front and rear.
The cockpit is a one-piece ICS Carbon Aero Gen 2 bar-and-stem unit developed with Tudor Pro Cycling Team. It's stiffer than the previous generation, designed to hold a low, aerodynamic position over long miles of rough terrain without punishing your hands and shoulders. The handlebar has 12 degrees of flare for grip and control when the surface deteriorates, with 135mm of drop and 81mm of reach — geometry for riders who want road-bike efficiency without sacrificing…
