Technologies used
In this chapter we explain the technologies that the manufacturer uses in this product.
X-Dome™ ™
The X-Dome technology creates an incredibly light, precise and robust cassette. The open design repels dirt better, giving you smoother shifting performance and longer component life.
XDR™
The XDR™™ driver is a universal interface for cassettes with single sprockets under 11 teeth. This allows lighter and more versatile drives to be implemented without the need for a new rear hub standard, a change in the hub body or the cassette tool. The XDR™ interface is 1.85mm wider than XD™ and was developed for racing use. The XDR drivers are compatible with all XD cassettes as long as you install the cassette with a 1.85mm wide spacer.
X-Range™ ™
Road bikes are faster and more capable than ever before, and riders continue to show what road handlebar bikes are capable of. X-Range™™ is the translation for the modern way of riding road bikes. SRAM has completely redesigned the road bike gear ratio, for more gear range, a more pleasant and better usable gear stepping and, thanks to AXS™, also smarter shift settings. With X-Range™™ you're always in the right gear.
