Sapim's CX-Ray bladed aero spoke is the leading choice of champions. CX-Ray spokes have an aerodynamic advantage over round spokes and build into lighter, stronger wheels.
With a weight nearly 30 percent lighter than standard double butted spokes, you would expect to give up strength. CX-Ray spokes withstand more than 3.5 million load reversals in fatigue tests, 3x more than any spoke on the road.
CX-Ray aero spokes are produced from high-tensile 18/8 stainless steel, which is ideally suited for the rigorous demands of spokes. Even downhill racers use CX-Ray spokes because of their strength and durability.
Weight: 32 spokes weigh 141g (32 x 264mm); 4.41g / spoke
Colors: black or silver
Even lengths: 182mm to 310mm
