• A new grade of stainless steel enables Sapim to reduce the diameter of the spoke, whilst increasing its strength and fatigue resistance. Effectively, the CX-Super is 17% lighter than the CX-Ray and its strength is increased by 120N in the middle section versus that of the CX-Ray.

    Despite the spoke hole problem, I guess the super cx ray is better and stiffer in description?

    It can't be stiffer, for practical purposes all steels have the same elastic modulus.
