Campagnolo Chorus shifter question
Hi everyone,
I recently bought a vintage 9 speed chorus groupset on ebay and have started building a 90's steel frame bike with all campy parts.
While overhauling, cleaning and relubing the shifter interiors i noticed that the left hand shifter shifts 12 times instead of 9.
Now, normally the left hand shifter is used for the front derailleur so only has to shift once so I reckon this won't be a problem but I was wondering if this is something that is particular to my shifter or par for the course with this set.
I've heard of swapping out ratchet disks within shifters to convert them from 9 speed to 10, 11 or 12 so that might also be the case with this shifter though I'm not entirely sure.
I'd love to post pictures but since this is my first post here, I can't.
Thanks in advance!

Yeah, lots of clicks (not all of them necessarily accessible once the cable is installed and everything has been adjusted).
The 12 clicks are not indexed to shifting events, just finely-spaced positions of cable/derailer movement.

Yes the left side will have finer, less obvious clicks than on the right hand -rear shifter. the front shifting isn't indexed. And BTW, should be 8 clicks on the right hand side for 9 speed.

correct, they have quite a lot of take up so they can be adapted to almost any setup - I notice the pic above where they are shifting a Shimano mountain bike setup !
the levers can be overhauled and I would suggest that you do this at least on the RH (rear) lever - have a new ratchet disk and spring put in, so you don't have to take it apart after you've assembled the bike.
there are videos about how to do this, and a competent shop should be able to do it for you, costs about $50 bucks per lever
Branford bike in seattle can do it for sure and they have all the parts. https://branfordbike.com/

I've found that even Shimano's triple STI left levers can be set up to work perfectly shifting a double, with no ghost positions, and with missing trim position(s) that prove unneeded every time.
And yeah, Campy's left lever even works fine operating primitive mech's like a 1960's Schwinn Sprint (Huret 700) or similar (shown below).
