I got one put on yesterday at a local shop in a kinda hurry but he put on something called Monsoon (who the hell are they!) and 7sp. It's a freewheel hub but needs a spacer/s but was £20 to much for it, it didn't catch the name on the box i got it off the cassette after getting home and didn't take it (box) as I was going straight out on it with some others but I feel it was to much for a name I've never heard of plus it's silver/ chrome, wheels (Mavic) are black... just wondered.
