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.

Technology

DUB

The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance. 

X-Range

Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. We completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.
