The new Kaius 01 is more aero, stiffer, lighter, and adds more tire clearance. Impressive.
Revised frameset weighs 1,469g total (998g frame, 400g fork, 134g seatpost), a 63g reduction.
3% greater stiffness and 4% weight savings over previous version.
12% improvement in bike-only aerodynamics and 1.05% system-wide speed gains with 45mm tires.
Tire clearance up to 52mm with ISO 6mm clearance, down to 32mm without pedal/ground clearance issues.
T47 x 85.5 threaded bottom bracket (not pressfit).
External cargo system with top tube bag mounts, Cargo Plate, AeroCore bottle cages, lower downtube mount.
1x specific drivetrain with chainrings from 32t to 50t, integrated chain guide.
Full Mount compatible UDH dropout for latest SRAM drivetrains.
Geometry: 5mm reduction in reach, 11mm increase in stack, 10mm additional ground clearance, 4mm additional trail, 5mm longer chainstays.
Available in six sizes (47-61cm) with ICS carbon aero cockpits.
No in-tube storage (external only).
Stiff fork and one-piece cockpit transmit big impacts on rough terrain.

One of the raciest gravel bikes gets even racier while adding some practicality.

Swiss manufacturer says 'certain fork steerer tubes have separated under heavy duty riding conditions' of its BMC Kaius 01 gravel bike.

The BMC Kaius 01 ONE definitely looks fast, and it’s light, too. So, does that mean it ticks all the right boxes for a gravel race bike?
Attention to detail
Uncompromising race bike
Lack of compliance
No power metre (given the high price)
May 2023 · Warren Rossiter
BMC’s flagship Kaius model is an ultra-light, racing, aero superbike designed for… gravel
Very light frame
Exceptionally fast in the right conditions
Great specification
Can be a handful on rough technical terrain
Jan 2023 · Sam Challis
The new Kaius makes gravel rides feel like road rides
Fast ride feel off-road
Comfort levels
Good attention to detail
Forward-thinking cockpit design
Quirky on-road handling
