E*thirteen TRSr Cassette Mountain Bike 11 Speed 9-46t SRAM XD 294g XX1

Up for sale is a nicely used e13 TRSr cassette in 9-46t range. Will work with any 11 speed drivetrain like SRAM or Shimano but does require XD freehub body. Most mid cage derailleurs designed for 42t will clear with no issues. Insanely light at just 294g including the plastic bushing and the lockring. This is the hard to find 1st gen TRSr cassette with the lockring instead of the pinch bolt. Not sure about the mileage but seems pretty low with no sign of worn teeth.
