TECHNOLOGIES

FULL PIN - FULL PIN technology uses eleven lightweight, stamped cogs held together with 123 high-strength stainless steel pins. The result: a cassette that's light, durable and equipped with SRAM's super wide gear range that's a perfect fit for any ride. The open design similar to our X-DOME cassette aids in mud clearance, giving you cleaner 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 rear axle standards, cassette tools or hub redesigns. The XDR interface is 1.85 mm longer than XD and is designed for road hub applications. XDR driver bodies are compatible with all XD cassettes when the casette is installed with a 1.85 mm 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-Rane, you're always in the right gear.
