Innovation often comes from places youd least expect. In order to make a lighter crankset, we made it bigger. To add stiffness, we used less material. The new SRAM RED 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 Glide R chainrings are optimized for use with the YAW Technology in the front derailleur, delivering seamless, flawless performance. Bottom Bracket NOT Included. Exogram technology uses a large, hollow cross section all the way to the spider, minimizing weight while maximizing stiffness. Our stiffest crank ever. Hidden bolt pattern leverages the characteristics of carbon fiber while presenting a sleek appearance. Stiffer X Glide R chainrings feature thicker construction, advanced shift timing pins and ramps, which are optimized for shifting with the YAW Front Derailleur.
