SRAM Cranks Red ETap Exogram BB30 50-34

The SRAM Red eTap cranks are larger but surprisingly lighter. Exogram technology uses a large hollow cross section to minimize weight and maximize rigidity and durability. The new construction carbon hole starts at the crank arm and extends into the crank spider, maximizing the weight-to-rigidity ratio. Its pattern of hidden screws makes better use of carbon fiber to further improve stiffness and lose weight. The impressive X-Glider plates have a thicker construction and are optimized for use with Yaw technology in the derailleur, achieving flawless performance without cracks.
For this new model the finish has been improved giving it a more sober touch with a Fullblack aesthetic.
