Ultegra wheel with chorus derailleur/ergoshift

Greetings to the group.

I am looking to combine the Shimano Ultegra WH6800 wheelset

With a chorus 8 speed rear derailleur and ergo shifts

Will a shimano 8 speed cassette do the trick??
If not, can I replace the freewheel on the rear hub to take the campy cassette??
Any support much appreciated!

I tried this with 10 speed and the short answer is it was troublesome. The long answer is that it will work, it will shift, but you'll never get the gears to be just right. Campy and Shimano use different spline patterns so you can't just replace the cassette, maybe you can replace the freehub body on some wheels but this is older stuff and may be unavailable. I've read that if you use loose cogs with the right spacers it may work, but again this was all relative to 10 speed not 8. Check the Sheldon Brown website as I believe it has all the compatibility info.

Where in the world did you get hold of a WH6800 and why would you want to use it with 8 speed Campy shifters? The WH6800 is an 11 speed and I believe not backwards compatible, so the chance of you using this wheel for anything other than an 11 speed would be very problematic if not impossible. Now if you meant a WH6700 the Campy 8 speed shifters will work with a several combinations of derailleurs and cassettes, but you will have to decide if you want the the top 8 cogs or the bottom eight..Here is a good resource https://www.ctc.org.uk/cyclists-libra...gears/shimergo

I have no idea how Campy 8-speed Ergo works with Shimano 8-speed. You're on your own, there. But here's what I learned about Shimano 11-speed wheels.

The 11-speed Shimano cassette is 1.85 mm wider than the 10-speed and Shimano says spacers will be available to mate the new wheels with 8-, 9-, and 10-speed Shimano cassettes.

Actually, I have a fuzzy memory of failing to mate a SRAM cassette to a 6700 wheel that was 10-speed only--that is, too narrow for 8- and 9-speed.

thanks for sharing your wizdom !

I am doing a new build around a columbus early 90s frame.

The group will be a period correct campy 8 speed chorus.

These wheels were for sale on a forum for a price that I could not just pass (I am assuming from a test rider/ reviewer).
When decals are removed due to colour combination they would not look out of place either.

From your responses though I am starting to realise that this is not such a good idea.

and before you ask, going for a full shimano 11 speed group is not an option!

cheers

George

Wheels Mfg used to make a respace kit so you could run a Shimano cassette with Campy shifters. I had that setup on my old Bianchi Campione D'Italia- 8s Mirage gruppo with a set of Spinergy Xaero-X wheels that were not available with a Campy freehub. It worked flawlessly. It was just a set of spacers that replaced the stock ones from the SRAM cassettes that I liked to use. Check their website and see if they are still available. They were aluminum and very reasonably priced.

I have a bike with Campy 8 speed shifters and derailleur and Shimano cassette. It worked but not very well. I then added a J-tec shiftmate and it shifts perfect.

so if you allow me to recap:

1) On the ultegra 11hub I should be able to to fit a shimano 8 cassette
2) With the help of the correct j-tec device I should be able to get my Campy corus 8 dearailleur/ergo shifter to shift fine on the shimano cassette

Should I get a 9 or 10 or even 11 cassette in order to be able to interchange my teeth range?? (by readjusting the cable and limit screws)?

I use an American Classic conversion cassette for 10 speed. Not sure if 8 speed is available.

That won't work. The 8s and up cassettes are all nominally the same width- the cogs are thinner and the spacing is closer to fit more cogs in the same space, so the amount of derailleur movement required is less in each generation. If you have 8s shifters, use an 8s cassette.

It would work if there was a Shiftmate for it, but no dice.
