The 52/58 is built for pure speed at race pace. Developed through ProjectSpeed, this wheelset is engineered to reduce drag, maintain momentum, and deliver maximum efficiency when speeds are high and effort is sustained.
The progressive 52mm front and 58mm rear profiles optimise aerodynamic performance while maintaining stability and control in real-world conditions. At speed, the 52/58 holds momentum effortlessly — translating power into forward motion with minimal loss.

The 58/65 is built for riders who prioritise pure aerodynamic efficiency. Developed through ProjectSpeed, this wheelset is designed to reduce drag to a minimum and maintain speed at the highest intensities.
With a deep 58mm front and 65mm rear profile, the system is optimised for sustained velocity — holding speed effortlessly on fast courses, in breakaways, and under race pressure. Despite its depth, stability remains predictable and controlled, giving riders the confidence to push harder for longer.
