SRAM has outdone themselves once again. The XX1 cassette is the first of its kind. The 11 speed cassette is a single unit cassette combined with an XD driver body. The XD is a new cassette driver body design that allows the use of a 10 tooth small cog and provides an improved interface with the cassette. The SRAM XX1 cassette also features X-Dome technology. X-Dome creates an incredibly lightweight, precise and strong cassette. The open design aids in mud clearance, giving you cleaner shifting, performance, and longer life.
