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!

It's normal, don't worry about it.

More clicks in the left shifter is better for the trim function of front derailleur to prevent the front derailleur cage chain rub while shifting across the rear cassette range.
