SRAM XG-999 Cassette
X-Dome Technology Available in Nine Speed - XG999 The revolutionary machined design of the XG999 cassette uses the same grueling manufacturing techniques that produced the XX as well as the PowerDome road cassette. With this XG999 cassette, seven of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise, and strong cassette. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.
