Go big.

The engineers at SRAM improved upon the first-generation Red crankset by going bigger, and ultimately offering a lighter, stiffer, and more precise crankset. Built with Exogram technology, the new SRAM Red BB30 Crankset uses a larger carbon-optimizing structure, which enables them to use less material without sacrificing stiffness.


The crankset features a considerably burlier arm shape than previous versions with a true hollow cross section. The design also allows SRAM to rotate the spider in order to utilize the large, sturdy crank arm as a bolt anchor and reduce the number of spider arms to four, giving the cranks a sleek, air-splitting profile.


The rotated spider also reduces deflection from shifting, which minimizes the previous generation's occasional tendency to hamper the precision and crispness of front shifts. To ensure compatibility with aftermarket chainrings, SRAM still uses a 130mm bolt circle diameter on the standard cranksets and 110mm bolt circle diameter on the compact cranksets.


SRAM’s stiff X-GlideR chainrings are machined from 5mm thick 7075-T6 aluminum and have been carefully modified to work with the 11-speed drivetrain. The chainrings feature enhanced shift pins and shifted ramp profiles to work seamlessly with the Yaw-caged front derailleur.
