The SRAM RED GXP crankset is an 11-speed carbon double for road bikes, with a GXP bottom bracket and 170 mm crank arms. The crank arms are hollow all the way to the spindle, and the hardware is hidden to make better use of carbon's stiffness and low weight. For smooth performance, the manufacturer recommends X-GlideR chainrings, which are compatible with the Yaw system.
The GXP bottom bracket requires separate cups, which are not included: check the type before installation. This version has 50-34-tooth chainrings, while the range includes crank arms from 165 to 177.5 mm, so choose based on your height and riding position.
