SAPIM CX aero spoke is the choice of champions and many teams at the Pro-Tour. Sapim CX-aero spokes made in Belgium have an aerodynamic advantage and unbelievably high fatigue test results. We build them into our lighter wheels to achieve durable and long lasting wheels which don’t need to be re-trued. Each Progress Wheel, hub and rim is designed with perfect spoke angle to release extra stress.
