No, don't think you can. the spacing is wrong.

Its not the spacing between cogs, it is the overall width of the Freehub, which should be the same for 7-8-9-10 speed. The only problem is 6 speed. I had a Zipp 440 rear until three years ago and ran an 8 speed cassette on it...and if 8 speed works, then 9 and 10 speed cassettes do to.

Is it freewheel or freehub?

Says cassette in the ad...

Looks like the 404 with the older Zipp font and in green color on the black carbon rim..

Who knows?
