TJD2011I installed this cassette on my new Mavic Open Sport wheel. It did indeed require a spacer to get the fit just right. I used bottom bracket spacers from my LBS and everything went fine.
This cassette works the way it should but I have mixed feelings. The other day at the LBS I was able to compare it to a similarly priced Shimano unit and the Shimano just looked, well, higher quality. Not sure if it matters, but the SRAM lost the beauty contest.
