    campagnolo 10 speed cassette (compatible) on Shimano 9/10 speed hub

    I'm building up a retro-classic using 10 speed Campagnolo Record. The wheelset I want to use has a Shimano 9/10 freehub. I've done some cursory research and found that a few companies make a "conversion cassette" to be able to use the Shimano freehub with the otherwise Campy driveline. So....

    My question is whether this conversion is as simple as dismantling a Shimano and a Campy cassette and using the Campy spacers with the Shimano cogs? Is it that simple? (for me this would be great news because I have a number of cassettes of both types to draw from so buying a new cassette for this one project does not sound desirable).

    Thanks in advance.

    I've never seen any such converter, though you can generally swap the freehub body so that your Campy cassette will fit without issue.

    Another option is to run a Shimano cassette with a Shiftmate.

    Right...yes, my first choice was to swap the freehub and I've put feelers out looking for one for this older wheelset. It's certainly easier to *not* be dealing with loose cogs & spacers when servicing a wheel or changing gearing. Just checked out the shiftmate site. Nice option there. Doesn't fit my bill of ultra-low cost & using parts on hand in my workshop, but not bad at all!

    American Classic (and someone else I think) makes a cassette with Shimano shaped splines, and Campy sized spacers and cogs. It worked fine for me.

    You want to make your own by mixing the 2 cassettes ?? Never tried it.

    Conversion cassettes work, have used the am class one and no problems. Maybe tiny louder because the cogs were made of SS but besides that it worked pretty good. Faster than dealing with spacers and adapters.

    yes, that's what I had in mind. That said, I'm thinking if the Campy is wider, then there may be lock ring problems once all 10 cogs are spaced out a bit more...maybe?

    Actually yes u will have that problem. The conversion cassettes have a longer neck lock ring.

    IRD makes different ratios of 10sp cassettes with campy spacing that will work on shimano hubs as well as making shimano spacing cassettes that will work on campy hubs, LBS can get them thru Merry sales out of CA.

    looks like the shiftmate is the best option if I can't find a proper freehub. Really, I'd rather just have the freehub because I have more ranges of Campy 10 speed to choose (I mean, on hand for me) from anyway. Either that or use a different set of wheels...heh!

    What kind of hub are you interested in converting? Some hubs can be converted with a new freehub, many cannot. It will depend on the hub manufacturer and model. If you can find the serial number on the hub contact the manufacturer directly and ask if they have a Campy compatible freehub that will fit. Another option is to (possibly) rebuild the wheel with a campy compatible complete hub. Many DT Swiss hubs can go either way.
    Wheels Manufacturing also make a conversion cassette with Shimano splines and Campy cog spacing. The problem with buying a conversion cassette is that you'll only have one cassette that will work and it will be expensive.

    FWIW, this is a ten or so (? got it from a friend) year old Rolf Vector Comp wheel/hub and from what I could find on the 'net it was made by DT Swiss but Rolf apparently has no interest in customer support for these older wheels.

    I have too many bikes, am too frugal, and value too much the ability to mix & match parts (even if this particular mix/match doesn't work out) on my bikes to imagine paying real money for a conversion cassette. Shiftmate still beats that option in my mind for the cost + the fact that the one I need could actually prove useful for other setups I may decide to run in the future on other bikes.

    Thanks all for the feedback & info.
