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. Our 43/30T chainring combo combined with a wide chainline increases tire clearance while providing ideal gearing for venturing off-road.
