Sapim CX-Ray Spokes – Lightweight Aero Steel Spokes for High-Performance Wheel Builds The Sapim CX-Ray is one of the most trusted aero spokes for lightweight, high-performance wheel builds. It combines low weight, excellent fatigue resistance and aerodynamic efficiency, making it a popular choice for road, gravel and MTB wheels. Thanks to its bladed aero profile, the CX-Ray reduces air resistance compared with classic round spokes while maintaining the strength and reliability expected from a high-end steel spoke. It is a versatile option for riders and wheel builders looking for a strong, light and proven spoke solution. The CX-Ray is available in both J-Bend and Straight Pull versions, depending on the selected variant. This makes it suitable for a wide range of hub designs and wheel concepts. The black oxidized finish gives the spoke a clean and technical look, while also matching modern wheel builds perfectly. Available in 2mm increments, the CX-Ray allows precise spoke length selection for accurate and professional wheel building.
