◂ Spokes ▸
High-end Sapim CX-Ray spokes are among the top-tier spokes on the market.
The Sapim CX-Ray spoke achieves a perfect blend of light weight, strength and flexibility, and delivers outstanding results in fatigue resistance testing.

Carbon Fiber Material Our carbon rims are manufactured using premium Toray T700 + T800 carbon fiber, combined with a stable resin system to ensure consistent quality and a lightweight structure for road cycling. |  |
Light Weight Design A carefully engineered lay-up structure using Toray T700 + T800 carbon prepreg enables a lightweight carbon bicycle rims. Excess material is minimized to reduce weight, while reinforcement around the spoke holes ensures structural strength. The result is low weight without compromising strength or stiffness. |
 |
Wider Inner Width With a 23mm internal width, these road carbon rims are optimized for modern 700×30C–35C tires and remain compatible with even wider tires. The increased width provides better tire support, simplifies installation and removal, and enhances traction and cornering stability. |  |
Aero U-Shape Profile The wide U-shaped rim profile offers improved aerodynamic efficiency compared to traditional V-shaped designs, helping to reduce drag at higher speeds. It also enhances airflow stability in crosswinds, while contributing to increased stiffness and overall structural strength. |
 |
Bead Lock Design Subtle ridges along both sides of the carbon rim channel—known as bead locks—help facilitate easier tubeless tire inflation. Combined with a hooked bead design, they ensure a secure tire fit and reduce the risk of blowouts. |  |
Tubeless Ready Tubeless setups are increasingly popular for road bike wheelset due to improved grip, lower rolling resistance, and enhanced comfort. All of our carbon clincher road rims are tubeless compatible while still supporting standard inner tubes. An optimized anti-burp profile ensures straightforward tire installation, removal, and inflation. |
