BIELAS SRAM RED E-TAP GXP 50-34

The Sram Red E-TAP cranks are larger but surprisingly lighter. The Exogram technology uses a large hollow cross section to minimize weight and maximize rigidity and durability. The new hollow construction bore begins at the crank arm and extends into the crank arm, maximizing the weight-stiffness ratio. Their pattern of hidden screws makes better use of carbon fiber to improve even more stiffness and lose weight. & Nbsp;
