The SRAM XX1 11-Speed Cassette XG1199 is an innovation contributing to SRAM's unyielding pursuit of performance.
The XX1 components are designed around a single-plate philosophy: simple, lightweight and brilliantly effective.
By preserving only one plate (available with a variety of toothsets) and increasing the number of gear ratios available on the cassette, we obtain 11 gears on a new type of cassette: 10/42.
These developments mean that cassette can be used absolutely anywhere, for XC MTB or Enduro use.
The XX1 cassette uses X-Dome technology, cast in a single piece, adding an 11th pinion with 42 teeth for even greater flexibility.
However, the starting 10-tooth pinion means that a specific XD freewheel body must be used with this cassette.
