I've got a set on my stumpy m2- they're very very nice but remember you have to buy the hub to go with them. It's another £100 ish due to it's 24mm through axle, and also because they're upside down, you have to have discs. I got lucky with mine on ebay £276 brand new with hub!!! (instead of £550ish!), but then realised I had to have a new wheel built up and buy a set of discs.....
