Any info on freehub/hub compatibility?

I had someone come in to the coop the other day and he wanted info on freehub compatibility. He wanted to know if a campy FREEHUB would be compatible with a shimano rear hub. I know from personal experience that there are a few different type of freehub attachments. Different "patterns" on the back of the freehub only mesh into certain hubs. Knowing this, and knowing how often campy stuff ISN'T compatible with other things, I said it probably wouldn't work. But I prefaced it with "I barely ever see campy stuff so I could be wrong."

Was I wrong? Is there info on what type of freehubs are compatible with what types of rear hubs? Is it as simple as it can get? Campy freehubs w/ campy hubs? Shimano compatible freehubs with shimano hubs? etc?

Mavic makes both Campy and Shimano compatible freehubs for their (road) wheels. And should you change your groupset, you can keep the wheel and only swap the freehub.

I think the Novatec brand is part of a group of after market hubs where basically the same hub is sold under several different names and use the same freehub.
I believe An old member here - Mr Rabbit - had some professional involvement with them and wrote a bit about what fitted with what.

Never seen any but Shimano branded hubs being able to use Shimano freehubs.
And there isn't full compatibility even within Shimano.

What is the actual goal? And what did the person have? Exact parts?

Many people have successfully used Campy 11s wheels & cassettes with an otherwise Shimano 11s drivetrain, and visa-versa, Shimano 11s cassettes with Campy 11s drivetrains.

Other configurations have slightly greater differences, but I've been exploring simply changing the spacing on a 10s Shimano cassette to run Campy 10s. I think 9s spacers will work, plus a 11s freehub.

Nope. A Campagnolo freehub won't attach to a Shimano hub. And as far as I'm aware, nobody makes a freehub with a Campagnolo spline pattern that'll mate with a Shimano hub.

Some hubs have freehubs available with either Campy or Shimano spline patterns. If the guy that came into your coop had a Campagnolo hub, Campy makes freehubs (for recent hubs at least) with their own spline pattern and freehubs that'll take a Shimano cassette. Just swap the freehub if you want to swap cassette type. Some third-party hub makers have freehubs available for both Shimano and Campy, too.

Freehub bodies are brand specific.

Though SRAM adopted Shimano's spline pattern and Shimano is the dominant type.

Campagnolo has several spline types they changed them as time passed.

Shimano also has several spline patterns and variations.
  • Uniglide,
  • Hyperglide,
  • The aluminum 10s splines.
  • Dura Ace Uniglide
  • Hyperglide with or without 11s groove.
  • Capreo 9T
  • 7 spd, (8/9/10 spd), & 11spd
Somewhat interchangeable, but not perfect.

Thanks for all of the information all. The guy had a campagnolo (wow did I actually spell that right first try?) cassette and was looking for a rear wheel to build up his fully Campagnolo bike. (Unsure what type of masochist would do that do themselves now-a-day ) I told him that we most likely only had wheels with shimano hubs (or shimano compatible hubs.) Although we did have one mavic wheel with a mavic hub. I think he tried looking it up to see if there was a campagnolo freehub compatible with it, to no avail.

go to C&V and you will see lots of people like campy.....and not just the old stuff.

Well...

I know the reverse is true. I have a set of Campy Sciroccos. I was running Shimano when I bought the wheelset, so I ordered the wheels with a freehub body for SRAM/Shimano cassette.

But I later changed out the drivetrain to Veloce, which meant I needed a freehub body for Campy cassette. (And I found one, and all is good.)

That said, different hubs take different freehub bodies. You have to check with the hub maker.

I was going to transfer the Shimano freehub from the Sciroccos and put them on a Bontrager/DTSwiss hub, but it didn't fit.

I think as a general rule you can be sure that a Campy branded freehub is not going to fit a Shimano hub and a Shimano branded freehub will not fit a Campy hub.

Third party manufacturers such as Mavic and DT Swiss (and many others) must be able to sell their wheels to either side. So, they will make a hub and it will have a Campy compatible body OR a Shimano compatible body available. Often these can be purchased separately and swapped out. Usually in the $80 - $100 range.

It also appears that Campy makes a Shimano compatible freehub body for Campy hubs as a replacement part. Once again, to allow a larger wheel market for sure.

I've been using Shimano wheels on my Campy 11s build

But, I also keep my eye out for good Campy compatible wheels on Craigslist and E-Bay.

They occasionally show up. One does, however, need to specify the newer 10/11s vs the older 8/9s, as both seem common.

If one finds a good deal on a wheel set (maybe off brand like Reynolds or something), then it will undoubtedly be cheaper than buying a Shimano compatible wheel and buying a second freehub.

Of course, another option is to get the wheels of choice, and buying a new hub, and rebuilding the wheel.

This type of masochist.

I've got bikes with both Shimano and Campagnolo drivetrains, and find that I like Campagnolo ErgoPower levers more than Shimano STI.

Seconded on preferring Ergos.

This should be compatible.
Mavic produces both Shimano and Campagnolo freehubs that can be screwed on its hubs.
Mavic Campagnolo Freewheel Body > Components > Wheel Parts > Freehub Bodies | Jenson USA

But Campagnolo hubs are of high quality and they are not super expensive.
