Is a 9-speed Shimano cassette close enough in cog width and spacing to a Campy 9-speed that it would work using Ergo shifters and Campy rear derailler? I have a rear wheel with Shimano hub that I would like to use on a bike with Campy drive train.
Thanks

AFAIK, No. unless yo have a lot of upper pulley sideways slop to compensate for the difference ,

and then I suspect you would hate the shifting performance.



There is a cassette driver made by Campagnolo to go on their hubs to use Shimano Cogs

the piece I saw last at $100 via Cambria Bike , but I've never seen one in the flesh.

You could potentially create a custom 9-speed cassette using this:

I ran a Shimano 9-speed rear wheel on a 9-speed Campy drivetrain for years with no issues. Could not detect any problems with shifting performance. Shimano 9-speed spacing is 4.35mm cog to cog, whereas Campy is 4.55. So a slight overshift. On the highest and lowest cogs, the limit screws force perfect alignment at the ends of the cassette. So the maximum misalignment is on the 2nd and 8th cogs, which if my math is correct is 0.2 x 3 = 0.6mm. This assumes you've correctly set up the derailleur so it is aligned to the middle cog. Too small to notice.

There will be zero shift misalignment if you run the later generation Campy 9-speed shifters (rounded hoods) with the older generation (years 1992 to 2000) Campy indexing rear derailleurs. Due to a fortunate coincidence between cable pull, cog spacing and derailleur geometry, this mix of the newer shifters and the older derailleurs results in perfect alignment for a Shimano 9-speed cogset.

This mix also allows you to mix Campy 10-speed shifters over a Shimano 10-speed cassette. Which I used this morning on my ride to work. Shifting perfection.

Thanks everyone for your replies so far. If any of you have further information, let me know

I used a Shimano 10sp wheel with my Campy Chorus 10sp shifters and was never quite satisfied. I used both unmodified. I have given up on this, mostly because I now have 2 sets of Campy wheels. IIRC there was a cogset that would fit Shimano wheels with campy spacing, but even that didn't work well because Campy wheels are dished differently (I forget if more dish or less than Shimano), although I never understood that as some wheels will take either freehub assembly. Which brings up another thing to try, if possible why not switch freehubs?

joejack951

My American Classic hubs are easily converted to Campy freehubs but they do have to be dished more for the Campy freehub. As far as I know, the same applies for any hub that is convertible except for the new 11 speed Shimano compatible hubs which are dished identically to Campy 9/10/11 speed hubs.

There are a few sources for cassettes like what you need, ie. Campagnolo spacing with Shimano splines, and vice versa. I believe IRD offers them, but you might find others.

zacster

That's what I'm talking about. But the IRD barely fits because of the dishing issue and may not clear the dropout. I think the thing that works is to remove one cog and use only 8 Campy spaced cogs and set your limit screws so that you have an extra click on the smallest cog.

Shiftmate FTW.
