Sapim CX-Ray J-Bend Spokes

Yes, these J-Bend spokes are designed to fit all standard hub hole configurations, making them a versatile choice for most custom wheel builds.

The CX-Ray features a bladed, elliptical profile that significantly improves aerodynamics by slicing through the wind. Beyond speed, the cold-forging process used to create this shape also increases the spoke's fatigue resistance and strength compared to traditional round spokes.

You can absolutely use them for both. While they are a staple in the road racing world, their high strength-to-weight ratio and fatigue resistance make them a popular, reliable choice for MTB and BMX wheelsets as well.

Double-butted means the spoke is thinner in the center than at the ends. This design adds flexibility, allowing the wheel to absorb road vibrations better and resist fatigue, which ultimately leads to a more durable wheelset.

No, these spokes are constructed from high-quality stainless steel and are specifically engineered to be corrosion-resistant, ensuring they hold up well even in challenging weather.
