SRAM XX Spider and Chainrings for Specialized S-Works MTB Crank

You like to upgrade your SRAM XX group with the ultra light Specialised S-Works Carbon MTN crankset without having to renounce the performance of X-Glide chainrings? - No problem with the particularly for Specialised designed SRAM crank spider. Perfectly suited for 2x10 drivetrains.

Imagine being able to shift smoothly at any time, no matter what. Truvattiv's talking full-power shifts. Up, down, whatever the trail demands. The benefit of the X-Glide drivetrain is simple, yet, when you think about it, incredibly impactful to the way you ride. Flawless shifting means you'll never again compromise your speed and power in unpredictable off-road terrain.

Here's how they did it: TRUVATIV's crank engineers threw away the old standards and developed a new chainring geometry from the ground up. They precisely paired the different-sized chainrings and redesigned where and how the chain engages with the rings. By aligning the chainring pick-up rivets to the chain pivot pin-rather than the middle of the chain link-you get double the shift opportunities.
