This is the ‘light’ version of the GX 11 Speed Cassette – it got an alloy 42t big ring, bringing the weight down to just under 330g (so close to the X1 cassette at 315g, and saves a bit over the normal GX at about 400g).
It’s got about 400 miles on it, but looks like plenty of life left. Needs a XD Driver hub!
