Innovation often comes from places you would least expect. In order to make a lighter crankset, SRAM made it bigger. To add stiffness, they used less material. The new SRAM RED 22 Exogram Crankset is completely hollow all the way to the spider. Its hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. The stunning X-GlideR chainrings are optimized for use with the Yaw Technology in the front derailleur, delivering seamless, flawless performance.
