Technology
X-DOME
X-DOME technology creates an incredibly lightweight, precise, and strong cassette. The open design aids in mud clearance shifting performance and longer component life.
XDR
The XDR driver body is a universal mounting system for cassettes that incorporate cogs with fewer than 11 teeth. It allows for lighter and more versatile drivetrains without requiring new rear axle standards, cassette tools, or hub redesigns. The XDR interface is 1.85mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the cassette is installed with a 1.85mm spacer.
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.
