The new Kaius 01 is more aero, stiffer, lighter, and adds more tire clearance. Impressive.
Revised frameset: 1,469g total (998g frame, 400g fork, 134g seatpost), 63g lighter than previous, 3% greater stiffness, 4% weight savings
Aerodynamics: 12% improvement in bike-only aero, 1.05% system-wide speed gains with 45mm tires
Tire clearance up to 52mm with ISO 6mm clearance standards
T47 x 85.5 threaded bottom bracket
External cargo system with top tube bag mounts, Cargo Plate, AeroCore bottle cages, and lower downtube mount
1x specific with 32t-50t chainring compatibility, integrated chain guide, UDH dropout
Geometry adjustments: 5mm shorter reach, 11mm higher stack, 5mm longer chainstays
Available in six sizes (47-61cm) with second-gen ICS Carbon Aero Cockpits
Stiff fork and one-piece cockpit transmit big impacts on rough terrain
No in-tube storage (external only, which may be a con for some)

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

May 2023 · Warren Rossiter
A bold statement in speedy race-orientated gravel that takes things to an extreme
Very light frame
Exceptionally fast in the right conditions
Great specification
Can be a handful on rough technical terrain

Good attention to detail
Forward-thinking cockpit design
Quirky on-road handling
