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. Mini Cluster: The MINI CLUSTER hybrid cassette construction combines four small cogs that are Cnc machined out of a single block of billet steel with an additional eight cogs that are individually pinned together. The Result: a cassette that´s light, durable and equipped with a gear range that´s a perfect fit for any ride. 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.
