The SRAM Red BB30 crankset raises the bar of what you'll expect in a crankset, with enhanced stiffness and chainrings that improve shifting. The crank arms are completely hollow all the way to the spider, which integrates the fifth bolt hidden in the crank arm for increased stiffness. This hidden bolt pattern makes better use of carbon fiber to further improve stiffness and shed weight. The stiff X Glide chainrings are CNC'ed from 5mm thick 7075 aluminum and feature improved ramps, first developed on the XX mountain group. The stiff crank and improved chainring design optimized for use with the Yaw Technology in the front derailleur, delivering seamless, flawless performance.
