The crank is the center of X-Range gearing philosophy. With tight 13-tooth gaps between chainrings paired to wide-range cassettes, riders get more range while shifting less frequently and staying in the big ring longer. Previously only available on RED, integrated chainrings are light, stiff, and incredibly durable. The black finish mated to dazzling glossy carbon arms will elevate any bike. Unique chainring shape results in a lighter weight, stiffer, more durable crankset X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear Crisp and accurate front shifts Carbon fiber crankarms for light weight and stiffness DUB bottom bracket adds durability and simplicity 50/37T, 48/35T and 46/33T chainring combos available Can be upgraded to a power meter SRAM Model ID: FC-FRC-D2 Attributes BCD Direct Mount BB Inclusion No Chainline 45mm Crank Spindle Diameter 28.99mm Crank Arm Length 172.5mm Interface DUB Crankset Material Carbon Pedals Thread 9/16'' Primary Color Black Speed 12 Drivetrain Spacing Road Disc
