Sram X01 11 speed Cassette 10-42
Sram's X01 11 speed cassette is essentially the same as the XX1 in design, just a step down in weight/materials. With the X-Dome and X-Glide technology still build into the cnc machined cassette you can be sure you won't loose any performance from this cassette. Only 15 grams heavier than the XX1, the X01 is machined out of 4130 chromoly steel with the largest ring is still made from 7075-T6 aluminum.
