[Closed] Campag 9-10s compatibility

I am trying to get an answer to this, and best i have got so far which may be wrong, is it depends, The new 10s mechs aren't compatible with old 10spd mechs, but old 10spd is compatible with old 9spd.

That may be wrong, and i do need a new rear mech so would like to know myself.

I should work. Cable pull is the same I believe which is the most important thing.

I can ask an expert mate in a lbs,

I'd presumed it would be common knowledge.

Virtually what mrmo says.
There is some info on Campagnolo site , but does not cover 9 speed

CAMPAGNOLO.COM "http://www.campagnolo.com/repository/documenti/en/Compatibility_table.pdf"

...but you could ask Campagnolo directly, or maybe RJ Chicken can advise.
