I have an older set of HED wheels with HED hub and Shimano-compatible freehub. The bike that the wheels are going on has a Campagnolo 9 speed group - brifters, derailleurs.

The Campagnolo-compatible freehub body for this hub doesn't seem to be available, at least I haven't found it in stock anywhere.

This is the 3 pawl freehub body, from (I think) 2009 to 2015.

Sheldon Brown says "With 7-, 9- and 10-speed systems, the sprocket spacing between brands is close enough that it rarely causes any difficulty in practice."

Has anyone used a Shimano 9 speed cassette in a Campagnolo 9 speed drivetrain? Does it work okay?

Alternatively, anyone know a source for the HED Campagnolo-compatible 3 pawl freehub body?

Or anyone know if other brands' freehub bodies are interchangeable?

Shimano cog spacing is 4.34mm.
Campy is 4.55mm.
I would expect if you set it in the "sweet spot" at gear 5, you'd have "some" noise in 1 & 9. maybe sooner?
If you don't use 1 & 9 that much, it may be "useable".

10 speed chain might reduce the noise.

No. It won't work well. I tried and it didn't no matter what Sheldon said. I used a Shimano 10sp wheel with a Campy 10sp system and no matter where I had the alignment, when I shifted up or down something would be between.

For my Wahoo Kickr Core trainer I created a 10sp cassette with Campy spacing from a Shimano Ultegra cassette by placing .2mm spacers between all the loose cogs. That worked, and look at the spacing that Bill provided above. That meant that I was out by .01mm, and that is well within the tolerance. Since not all had spacers because the large 3 cogs are fixed together, I had one gear, the 9th, that isn't within spec but it still didn't matter. The tenth worked because of the limit screw.

M touring bike has Campagnolo 9-speed Mirage Ergo Levers and 9-speed Mirage rear derailleur and 9-speed Shimano cassette and it shifts across the entire cassette with no problems. As a poster mentioned previously, I set mine up on t he center 5th cog.

Apparently Miche (and others?) used to make cassettes with Shimano splines but Campagnolo spacing. Can't find these any more.

I guess I'll try a Shimano 9 spd cassette; if that doesn't work I'll try adding spacers; if that doesn't work I'll get a Shiftmate.

JTek Shiftmates offer a lot of mix and match options. I've run them on many bikes for thousands of miles with no issues. I run a mix of Ergo 9 speed levers, Shimano 9 speed cassettes and either Campy or Shimano rear ders. Of course the Shiftmate pulley is different, they have quits a number of pulleys to "translate" various cable pulls to shifting outcomes. Andy

I've tried to do this as well and although the shifting works OK when you set it up, it is very finicky and after a few weeks the shifting gets progressively worse until you tune it again. This gets tiring very quickly.
However, I have made it work but the solution is not quick or easy. My setup is Veloce Ultrashift series 2 shifters (rounded hood tops), Shimano 11spd rear derailleur and Shimano 9spd cassette. This combo almost works but it still suffers from bad shifts after usage as the shifters pull too much cable per shift.
Solution 1: Disassemble the right shifter and where the cable wraps around the ratchet, grind a groove so it pulls less cable (I used a dremel). How deep? I don't know - I just ground in a groove (along red-dotted line) and it was spot on and my setup works perfectly and even after 2 years has never missed a shift. Note- disassembling/re-assembling a Campy shifter is not an easy task.

Solution2. Get an 11spd compatible hub. Buy a cheap 9 spd cassette where the individual cogs can be separated (the more expensive cassettes have the cogs joined together on an alloy carrier). Cutout shims using clear plastic sheets used in photocopiers (available at Staples etc) and place them between the cogs. As this widens the cassette you need a wider 11spd hub.

As Andy said for $40 and a few mins to install a Jtek Shiftmate #1 you will have Campagnolo 9 speed shifters and Campagnolo RD run as smoothly with a Shimano 9 speed cassettee as with the Campagnolo cassettee. I have not done the 9 but have used the #1 for years on an 8 and recently on a 10 Campagnolo groupset with Shimano free hug/cassettes.

Edit: Should have added I believe SHiftmates also improve the cable line into the rear derailleur.

Solution3. Get a Campy compatible wheel and just use things the way they are meant to be used. While I was able to kluge a 10sp Campy setup on my trainer with the Shimano 11 freehub and have it work well, I still wouldn't want to ride such a setup outside. And as in solution2 above, it only works because it is an 11 speed freehub which isn't what you have.

I've dealt with these things a few times on my Campy 10sp bike, and nothing worked properly at all until I used an 11sp Shimano freehub, other than native Campy. And guess what, the 11sp Shimano wasn't even made when I was dealing with this originally, only about 5 years later. And yes, maybe a Shiftmate will work but then you can't swap wheels. And Miche did make a Campy cassette but it didn't really fit on a 9 or 10sp Shimano hub. All of the solutions out there can be made to work but none work nearly as well as Campy on Campy.

Sure if your other wheels don't have the same cassette spec. But then most would say that the second wheel isn't compatible and thus shouldn't be interchangeable anyway. I have a number of bikes with the same 9 speed cassette spec and they all interchange even though different Shiftmates are used to translate between the other drivetrain parts. Andy

Budget for this build requires used wheels and the selection of used carbon wide/deep tubular rims in very good condition with Campy freehubs is limited.m to say the least.

The bike won’t ever see a wheel swap.

Welcome to the world of Campy. But you can find things out there if you keep looking. Just remember to type in the secret password on eBay and all the Campy stuff is revealied.
