Racing Spec 5.2 is built with solely one objective in mind – bunch sprint victories. Refined to perfection, the new generation 5.2 has significantly improved in terms of aero efficiency, lateral and torsional stiffness, and weight from its previous generation.

The newly designed 26 mm wide aero profile rim combined with TORZC second-generation Ultra Smooth Carbon Fiber Moulding Technology has created a highly responsive 55 mm depth wheel with excellent aerodynamic efficiency at high speed. The rim width is designed to equip wide tubeless tires, optimized to host tubeless tires up to 30mm. You will handle all technical sections and bumpy pavements at ease with reduced rolling resistance.
