Shimano - Campy mix compatability(10 posts)

Shimano - Campy mix compatability'mmm Donuts!
Jul 23, 2001 8:47 AM
Are Shimano and Campy at all compatable? Is it possible to do a gradual chage-over from Shimano to Campy?

Thanks for the tips!

The Campy and Shimano drivetrains are completely different. You cannot do a gradual upgrade from one to the other.
I wouldn't go that far...TJeanloz

Campy and Shimano are completely different but are marginally compatible. Let's assume that you currently have a Shimano 9s drivetrain and want to go to a Campy 9 or 10. You could replace the rear hub and cassette to Campy9. Cima, I know you're quite sure that this won't work and will cause all kinds of problems, but my shop experience tells me that it will. This leaves us with shifters and derrailluers. You could then replace the shift levers and rear derrailluer, keeping the shimano front d. Because the Campy front shifter is practically indexed, it works fine with a Shimano derrailluer. Lastly, you can change the front derrailluer. Cranks won't really need to be changed. You'll likely need a new chain when you switch cassettes.

If he wants to go with Campy 10, it would be a waste of money to get a temporary Campy 9 cassette, then buy a Campy 10 cassette when he gets the rear derailleur, Ergo levers and chain.

The Campy 9 cassette spacing is different than Shimano 9, so getting the wheels and cassette first will still cause shifting issues. The STI cannot fine tune to each cog of the Campy nine cassette.

The cranks should be changed out because of the need for the narrow chainring and chain ring spacing for the C10 chain. If he were to go with Campy 9, this could wait.

The man never said anything about going to Campy 10. Campy9 is still a perfectly current grouppo, and it would be an upgrade from anything Shimano :). Even so, he could pick up a real crap OEM Veloce 9 speed cassette for pretty cheap.

Campy 9 is different from Shimano 9; Blah, Blah, Blah. I know I'll never convince you, I know. But for others out there, I can assure you that it works. I have personally set up at least 25 different bikes like this.

Even with 10 speed, my experience is that the 10speed chainrings are not essential. My Campy10 chain is running perfectly on TA 9speed chainrings.

I have 6 sets of wheels and they are all 9 speed
2 sets campy record and 2 sets Dura Ace and 1 helium and 1 world class

All the wheels are interchangeable with both shifting mechanisms and never an issue except for a note i have on my notice board to turn the barrell either way a certain amount of turns if i use each wheel on different bikes.

I know hte spacing is a little different but your rear deraileur is not a super precision unit and will self adjust to an extent. SO sometime real life situations dictates over thery and numbers in the book.

theoretically, no.
but here's something that I've gotten to function. The shifting isn't great, but it is functional.
(providing you are going from 8-speed to 8-speed or from 9-speed to 9-speed)
Shimano: Cassette, chain
Campy: R.Der, right shifter.
The cranks can be either-or, but shimano works better
the left shifter and front derailur can be either-or as long as they are the same (campy-campy, shim-shim, but not campy-shim).
The braking systems are virtually the same, so it really doesn't matter if you mix and match for a bit.
That being said, here's the way to go:

1: new shifters/levers and derailurs
2: new cranks, cassette(and r.hub), chain
3: new brakes

Don't try this without the assistance of a talented mechanic, not some weekend-warrior "sure, I can fix your bike, I've got tools in my garage!" putz.
hope all goes well.

You'll also need to change bottom brackets. From splined to square taper.

It will likely work, depending on what you do, and when, however, nowhere near optimally. Little things like the chain design and teeth for all the rings are different. They could be loud and/or cause unusually high levels of wear.
I've looked at rebuilding casscyclopathic

You can get Shim cass (105 or lower) and rebuild it to work with Campy shifters. THere's a company selling spacers /sorry dont have URL/. This would allow you to run Campy comp cass on Shim freehub, more choice of wheels

But generally answer is no. PLus doing upgrades will cost you a dear penny. WHy all that headache with gradual upgrade? is cost an issue?

You'd better off selling your Shimano bike and buying new Campy bike /I am serious/. If you're attached to frame buy Campy bike, swap groupo and sell the bike. Buy used and you should almost break even good luck

Hello???? Components are much more than drive train. Yes you can mix. The headset doesn't care what the hubs are, and the hubs don't snub the foreign drive train.

You can, at a MINIMUM, swap the drive train, and wait for the rest to need replacement.
