Sapim's CX-Sprint offers many of the same benefits are the more expensive CX-Ray: an aerodynamic, bladed profile, unparalleled, tensile strength and fatigue life, and light weight. While a little heavier (about a gram) than the CX-Ray, the additional mass brings greater strength, stiffness, and durability, making this an ideal spoke for heavier riders or just a little added stiffness on the drive-side.
