I'm setting up an older bike with a used Campagnolo Chorus hub and 9 speed Campy cassette. A new Dura Ace 9 speed chain will work ok, won't it?
Spacing isnt a problem, wondering about parts compatibility.

Is there a special way to drive in those odd chain pins?

Thanks for input.

As far as running goes, any chain of the right width will run on any cassette, because the critical dimensions are highly standardized.

However chain plate profiles are highly sculpted to work with the shifting gates each company cuts into their sprockets, and mixing brands mightaffect shifting slightly. There are also reports of various chains being noisier than others, but I believe that's more a matter of cassette differences and chain lubrication than the chains themselves. Use whichever chain you prefer and care for it properly and you'll be fine.

Shimano makes a special chain tool for guiding their pins in, but you can use a standard chain tool if you're careful to keep everything perfectly aligned.

This might not be a good idea. The cassette might wear do to the parts being wrong. It might be a good idea just to go and get a new chain for your local bike store.

It depends on how particular you are when defining "OK"

Campagnolo retained exposed chain pins through the 9-speed era, with the exadrive cogs designed to engage the chain pins first. 10-speed chains with flush pins don't shift as smoothly on the exadrive cogs as they do the newer ultradrive design made for flush rivets.

Shimano switched to flush-rivets with the move to 9-speeds so one would expect lesser shifting performance.

Thanks Drew, for details. This chain is Dura Ace 7700 UG, not flush rivets, so I suspect it will work ok. Maybe it's really an 8 speed chain, though I was told 9.
