SRAM X01 XG-1195 11-Speed Cassette

Machined from a single 4130 chromoly ingot, the main body of the Sram X01 11 speed cassette is a sight to behold, and that is before we have even got on to the behemoth that is the 42 tooth aluminium constructed cog which is press-fitted to the main body. A true beauty the Sram 11 speed cassette is constructed almost identically to that of the XX1, however uses a slightly different finish giving it the unique stealthy look (if you can call a cassette this size  - stealthy ) The X-Dome structure of the X01 gives you a wide spread of speeds (10-12-14-16-18-21-24-28-32-36-42) whilst keeping the jumps between them nice and even.
