SRAM XG-1099 Cassette

Information from: http://www.sram.com/sram/mountain/products/sram-xg-1099-cassette.

The revolutionary machined design of the XX Cassette uses the same grueling manufacturing techniques that produced the PowerDome road cassette. With X-Dome, eight of the cogs are CNC-machined together out of a single block of billet steel, creating an incredibly lightweight, precise and strong cassette. It’s a process that takes nine hours per cassette! You have never seen a cassette that looks like this. The open design aids in mud clearance, giving you cleaner shifting per-formance and longer component life.
