01 / C1 RS
Race Focus
A race-focused setup shaped for speed, acceleration, and direct power transfer without sacrificing control.
Race geometry
Light carbon
fast response
CIRON / C1
Engineered for the pursuit of speed.
A performance bicycle developed as one complete system, where carbon architecture, aerodynamics, and rider control work together.
Philosophy
Performance should feel effortless
From geometry to carbon layup, every decision is made to deliver speed with confidence and control.
Craft
Carbon architecture
Each carbon layer is positioned to balance stiffness, compliance, and efficiency under real riding conditions.
Innovation
One integrated performance system
Frame, wheels, cockpit, geometry, and rider position are developed together so every part supports the same riding experience.
Evolution
CIRON C1
A complete performance platform for riders who want speed, precision, and control without distraction.
// Integrated system
Performance, Engineered As One.
CIRON develops rim profile, hub geometry, spoke tension, and tire volume as one complete system. The result is a wheelset that feels fast, quiet, and composed in real conditions.

// Private configuration
Refine the ride, down to the detail.
Every CIRON build is shaped around model, fit, terrain, and ride feel. The process stays simple, but every decision has a clear performance reason.
01
Select model
C1 RS / C1 / C1 X / C1 GRStart with the platform that matches the ride: pure race, everyday performance, all-road versatility, or gravel endurance.
02
Dial in fit
Geometry / position / cockpitFrame size, cockpit length, saddle position, and reach are treated as part of the performance system, not an afterthought.
03
Tune the system
Wheels / tires / finishWheel depth, tire profile, carbon finish, and component package are selected to support the same ride character.
04
Deliver the build
