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.
As light as a titanium spoke, the CX-Ray still receives the best results in fatigue testing of any spoke. Its unique strength and flexibility make the CX-Ray suitable for most bicycle disciplines. The middle section of the spoke is drawn then pressed in a special mold to form its specific profile. CX-Ray spokes are used by top bike racers and triathletes around the world. Even downhillers use them, recognizing their strength and flexibility. Special alloy treatment and sophisticated production make this all possible.
The CX-Ray fits is all standard hub holes.
