Inside the Testing Center.
Straight from the factory floor. where your frame is built and beaten before it ships.
The material itself.
Our frames use Toray T800 / T1000 / T1K high-modulus carbon. the same fiber classes engineered for aviation-grade structures, laminated for stiffness where you sprint and compliance where you sit.
Threaded T47 bottom brackets (no press-fit creaks) and standard-size sealed bearings. any bike shop on earth can service it, years from now, without depending on us.
Every bike is assembled complete, gears tuned, brakes bled, torque-checked. then partially disassembled only to fit the box. You finish 4 steps at home.
