CX-Ray is Sapim's most versatile aero spoke. Sapim claims the CX-Ray has the highest fatigue test values of any spoke available.  Its unique strength and flexibility make the CX-Ray suitable for most high-end bicycle disciplines from road racing to Triathlon and even Downhill.   

The CX-Ray fits all standard hub holes due to it's 2.3mm maximum dimension at the widest portion of the blade. With a weight nearly 30% lighter than standard double butted spokes, it is almost as light as Titanium. 

CX-Ray aero spokes are produced from high-tensile, fatigue-resistant 18/8 stainless steel, ideally suited for the rigorous demands of cycling.

These spokes came blazingly fast thanks to the incredible customer service at Wheelbuilder! They saved the day and the event.

Review

i worker in shops for 11 years ( built up hundreds of wheels) These are my favorite spokes to use. You can see the direction of the oval so that when it's pointing forward the spoke is sitting where it belongs and will not shift if you pre stress the wheel.
