Speed Unbound
innovationGravel 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.
Integrated Cockpit System (ICS)
The aesthetic simplicity and innovative functionality of the Integrated Cockpit is the epitome of Swiss engineering and design. ICS keeps shifter wires and brake lines in their place: out of sight.
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.
