The crank is the very center of our 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, our integrated chainrings are light, stiff, and incredibly durable. The black finish mated to dazzling glossy carbon arms will elevate any bike.rider. Always find the sweet spot.

X-Range gearing technology gives you more range and a smoother gear progression, so you’re always in the right gear
