The revolutionary machined design of the XX Cassette uses the same gruelling 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 performance and longer component life.
SRAM's best cassette at an almost affordable price. What else could one ask for?
Great cassette, its light weight and quality CNC machining is immediately evident when pulling it out of the package. I've had good shifting with the XX installed and confidence that the gear I want is the gear I'll get.
Fantastic Cassette - extremely light, perfect shifting even in the worst conditions and lasts a long time.
Excellent item.Extremely light.Very good value.
