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! The aluminum large cog can be
replaced as needed. You have never seen a cassette that looks like this. The open design aids in mud clearance, giving you cleaner shifting performance and longer component life.

Fast, accurate, percise are all good descriptions for the XX series cassette from SRAM. Plus this thing is a work of art with its one piece construction...still dont know how they do it!

Pros
Uber light weight. This cassette is half what a regular cassette weight. The open design helps eleminate crud build up
Cons
High cost. Tends to make a bit more clunk noises due to it's open design.
Review
Super light weight cassette, perfect the elite rider or the person who just wants the best and lightest. The only down side comes when its time to replace. Performance is great as the shifting ramps efficiently shift up as well as drop down. The open design allows a major amount of crud to fall through without packing in between the gears.
