This is a nice piece of gear. Very lightweight, impressive to hold in your hand as you appreciate its machining. My 11-32 version shifts nicely with etap wifli. It's hard to call it a good value at its price but for weight-weenie builds it's the way to go.
I have a few of the previous XG-1190s in various sizes and weigh them all. I was rather disappointed when the 11-28 cassette came in at 168g which is 10 more then my other two 11-28s. The new version is Identical to the old with the exception the back no longer has a 22 and the words Sram and Red switched places. Don't get me wrong it's still a great cassette as the original XG-1190, but I was under the impression there was something new and I was gonna shave a couple grams on my new build.
