XG-1099 10spd Casssette - Lightest 10spd MTB Cassette Available

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.
