I have a 10 speed Shimano style freehub wheelset I want to use with a 10 speed Campy drivetrain. What's my best course of action here? I can think of two solutions.

1. Switch out the freehub body with a campy one. This seems easy in principle, but are there complications I'm not thinking of? Will I have axle length/dish problems?

2. Get a shimano splined/campy spaced cassette. These exist, but sourcing may be difficult and it limits my cassette choices.

Any other suggestions?

I recall a shimano splined Campag made freehub driver, but that was long before they bumped the cog count up to 10 or 11 speeds ..


N+1, build a Shimano drive train Bike and have a separate Campanolo drivetrain Bike.

Those are basically your options.

As to whether you need to redish or not depends on the hub...Shimano made their 11-speed generation gear requirements wacky with spacers and sometimes re-dishing. You probably won't need to. Whether you can swap freehub bodies depends on the hub and if the manufacturer has a campy splined freehub available.

What are the wheels? If a freehand body is readily available, that's your best bet. If you have plans to keep this bike a while and ride it enough to wear out the next cassette, a conversion cassette is not a great way to go- they're already tricky to find for 'legacy' cog counts, I don't foresee that changing for the better.

Another option may be a Jtek shiftmate. I have no idea if a campy to shimano 10s to 10s exists, but that kind of conversion is right in their wheelhouse.

E: you need a shiftmate #1. Click on 'compatibility guide' to see what I'm on about

Get a Campagnolo indexing rear derailleur made from 1992 to 2001. 8 or early 9-speed generation. At any one time there will be dozens of these on Ebay. Install and also use a 10-speed Shimano cassette.

The older derailleur geometry compensates for the slightly closer Shimano cog spacing. It will index perfectly. I have several bikes running this setup - for years.

Best of both worlds: cheaper and more available Shimano wheels and cassettes. Superior Ergopower shifting.

if you can swap free hub bodys, do that.

Knowing what you have would help, there are some wheels you can convert (by swapping the freehub), knowing what you have would assist in knowing if your are one which can be.

Hubs are Shimano 600 Tricolor. 6201 is the model, I think.

There is no such thing as a Campagnolo-spline freehub for any generation of Shimano 600 hub. And since 10-speed Campagnolo cog spacing is somewhat wider than Shimano, I doubt a Campy-spaced cassette using Shimano cogs would fit on the freehub. Too wide.

Finally, it is unlikely that a Shimano 600 freehub will accept an 11-tooth cog, as found in many of the Shimano 10-speed cassettes. 12 tooth is the smallest.

You could put a Shimano 8-speed cassette on there, and a Shimano RD. That setup will work perfectly with your Campy 10-speed shifters. I've done this a bunch of times with excellent results. See: Rear Shifting | CTC

Another more involved option is to rebuild the wheel around a Campy hub. You might be able to re-use the spokes.

There is no way you're going to fit a Campy freehub or cassette on that 6402 hub.

It's called a conversion cassette. Shimano hub with Campy spacing. I've been running wheels this way for years. It's awesome. and no swapping freehub body or shiftmate nonesuch:

heck, if you're nice, you might talk me out of one (12-28) ...

It's not the RD that's the issue, it's how far the shifter pulls/releases cable.

I used one of those with absolutely no problems. It was seamless.

The OP wants to use a Campagnolo 10-speed shifter with a Shimano freehub. Shimano freehubs naturally take Shimano cassettes, for which Shimano cog spacing is closer than Campagnolo spacing. Specifically:

• Shimano 10-speed spacing: 3.95mm cog center to center.
• Campagnolo 10-speed spacing: 4.12mm

Further, derailleurs have different mechanical advantages, that is the amount of travel per unit of cable pull.

• Shimano (non Dynasys and old weird Dura-Ace): 1.67
• Campagnolo 8/early 9 speed: 1.43
• Campagnolo late 9 speed and 10 speed: 1.50.

So in 2001, Campy changed the mechanical advantage of their rear derailleurs. God or Valentino only knows why.

So, if you have some Campagnolo 10-speed shifters (that pull on average 2.75mm per 'click'), and a 8/9 speeed Campy rear derailleur, here is the math:

2.75 x 1.43 = 3.93.

Perfect. As I posted, it works on paper. And after years of riding this setup, it works in practice.

Well I just learned a bit. Thanks!

You're welcome! Here is a fountain of all knowlege with respect to mix 'n match indexing:

In a few cases I think I have more accurate numbers than these folks, but overall this is a great reference.

Today I am commuting on a bike with Campy 9-speed shifters, driving a Simplex rear derailleur over a 7-speed Suntour Winner Pro freewheel. Works great.

Knowing the numbers is the basis of wisdom.

Cassettes are wear items and the conversion ones are expensive (except Ambrosio). Using a shiftmate, old Campy derailleur, or an 8 spd cassette (cheap) might be better. Someone out there also sells a converted SRAM derailleur...
