I have sram cassettes on my road wheelset and cyclocross wheelset. Both work great and were a great value. Cant see why someone would pay more for a cassette.
I wore this cassette out with over a 1000 miles before having to replace it. Took my Bike out for a ride and was not able to climb a single hill before the chain started jumping real bad. Had just replaced the chain and I should had replced the casette. But live and learn.
