Innovation often comes from places you would least expect. In order to make a lighter crankset we made it bigger. To add stiffness we 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 & shed weight. The stunning X-Glide R chainrings are optimised for use with the Yaw Technology in the front derailleur delivering seamless flawless performance. Exogram technology uses a large hollow cross section all the way to the spider minimising weight while maximising stiffness. Our stiffest crank ever.
