Question

Is a campagnolo 10 speed derrailleur compatable with 9 speed drivetrain?

Answer 1

yes, this will deffo work

Answer 2

depends on what part of the system you are talking about

9 speed entails 3 gears on the wheel and 3 on the crank

10 speed entails 5 gears on the wheel and 2 on the crank

the chain is slightly thinner in this system and the wheel may be wider

Answer 3

Ignore Andy T.  He obviously has no idea of what you are referring to.

In theory, since indexing is in the shifters, not the derailleur, a 10 speed campy derailleur should work with a 9 speed drivetrain.   You might have to do a lot of tinkering with the adjustment screws to get it right.  Also a 10 speed chain is narower than a 9 speed chain.  If the chain is not properly engaging in the jockey wheels of the derailleur, you'll need to get some 9 speed jockey wheels.

Hope this helps.

Answer 4

Yes the derailleur will work. Just need 9 speed shifters which I think you know.

Answer 5

Yes. There was a big break from 8 to 9 speed so not much is compatible. However from 9-10 speed, the same derailleur, rear wheel hub and front derailler should work. Like others said, you still need the 9 speed shifter. The shifters are the same except for the ratchet wheel so you can actually convert them if you just buy a new ratchet wheel.
