That's a good price for the Mavic cassette. I've used a couple of them.
Mavic made wheels with three different freehubs - a campag, a shimano and their own m10 (I think they called it that). The campag and the m10 were the same width but the shimano freehub was about 3mm narrower. 10 speed campag and mavic cassettes are wider than the old shimano freehubs. A mavic cassette will only fit on an m10 freehub and will not fit on a shimano.
The clever thing about the ambrosio 10 speed campag spaced/shimano splined cassettes is that the big sprocket is indented so that it will fit on a shimano freehub. Phew. I hope that makes sense.
In a nutshell if you an m10 the mavic cassette will be fine but if you have a shimano you will need an ambrosio cassette to run campag spaced 10 speed.
