Sram XX1 XG-1199 Cassette 11 speed - 10-42 teeth

The Sram XX1 Cassette with 11 speed ranging from 10 to 42 teeth. Except for its largest cog, which is aluminum, the entire one-piece unit is machined down close to its final shape from a steel ingot, a process that takes place in a single, labour intensive step. The dinner plate-sized large cog is a separate aluminum unit that is held in place by way of pins machined into the backside of the 36 tooth steel cog. SRAM also forgoes using a traditional lockring to hold the cassette onto XX1's proprietary XD driver body, with a clever system where the tube running down the center of the cassette features threads on its inboard end that mate to threads on the driver. A standard cassette lockring tool can still be used to tight or loosen the cassette.
