Mixing Campy Chorus 10s. with DA 9s. cranks

I actually ride a bike with a full Dura-Ace 7700 9 speed drivetrain and I plan to replace the actual brifters, brakes, derailleurs, cassette and chain with Campy Chorus 10s while keeping the DA crank and bb . Will these components work properly together? Thanks!

Campy front brifters aren't really indexed like Shimano's. They have several clicks that move the front derailleur incrementally so they can be used with just about any crank.

Yeah, so you might want to think about keeping the Dura-Ace front der. It might shift the Dura-Ace cranks better than Chorus. Since Campy front brifters are derailleur agnostic they pretty much shift any derailleur. In the end, though, either one will probably work just fine.

Thank you guys for your input. I understand that a Campy brifter will activate the front derailleur (either a campy or shimano one) differently than a Shimano STI one but in the end, the chain will shift correctly if not perfectly. One more question, is there a specific issue with using a 10s Campy chain on DA 9s chainrings? I've been told that a 10s chain is narrower than a 9s one...

Nope.

Thank you again for the input. See no offense but I frequently miss Sydney's wiseful opinion. May he rest in peace. I'll have a thought for him on my first ride of the season probably at the end of March, as soon as this creepy snow melts away here in Montréal .

This place won't ever be the same without him.
