The new Kaius 01 is more aero, stiffer, lighter, and adds more tire clearance. Impressive.
63g lighter frameset
3% greater stiffness
12% improvement in bike-only aerodynamics
1.05% system-wide speed gains
Up to 52mm tire clearance
T47 threaded bottom bracket
External cargo mounts for quick access
1x specific with UDH dropout
Aggressive geometry with reduced reach and increased stack
Feels light and agile on climbs
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.
