Sapim Aero spokes not only give an aerodynamic edge, they also make wheels lighter and stronger. Forging the spoke in one go in elliptical dies give much better aerodynamic characteristics than just flat spokes. The forging process brings additional tensile strength into the spoke.
Aero spokes are produced from the best suited stainless steel for spokes: high-tensile, fatigue-resistant 18/8 stainless steel conforming to Sapim quality standard specifications. The CX-Ray fit easily into all standard hubs.
