Speed Unbound
The innovative premium carbon layup uses ultra high-module fibres for unmatched stiffness resulting in maximum power transfer and minimal weight. Kaius boasts our Tuned Compliance Concept Race Technology for a comfortable ride on rough surfaces.
Gravel Race Ready
Kaius: the fastest on gravel. The geometry features a longer reach to improve stability and increase traction. It's designed for 1x or 2x drivetrains and complies with SRAM Full Mount for UDH dropout or Hangerless Interface derailleurs.
ICS Carbon Aero Cockpit
The ICS Carbon Aero Cockpit, with its progressive and aerodynamic shape, is the perfect match for this bike. Featuring a narrow top width, allowing an efficient aero position with a greater width at the drops providing incredible control at high speed.
Aerocore Design
Kaius comes in at the highest level of functional integration with our Aerocore design. This evolved solution integrates the bottle cages into the frame to optimize aerodynamic performance.
