A new generation of bike

We build aero carbon bikes for road racing, time trial and triathlon, with performance the biggest factor.

AF1 - Speed matters

Slim aerodynamic tubes, a stiffened tapered head-tube and over-built bottom bracket are the factors that make the AF1 a true competition frame.

Time Trial / Triathlon Frame

This Time Trial/Triathlon module represents the pinnacle of our aerodynamic technology. With aerofoil and kamm tail tube profiles throughout, it boasts superior aerodynamics to minimise drag and save important watts in a time trial or triathlon bike split.
