The crank arm is the core of the X-Range shifting philosophy. With tight 13-tooth spacing between chainrings paired with wide-range cassettes, cyclists gain greater range by shifting less frequently and staying longer on the main ring. Previously available only on RED, the integrated chainrings are lightweight, stiff, and incredibly durable. The black finish paired with dazzling glossy carbon arms elevates any bike.
