front derailleur

Hi folks
Couldn't find answer on search so had to post my schoolboy question. ...
I'm doing a component swap to an audax mk 3 frame (just bought a s/h frame)and wondered what band size I need on the front deraillear? My 32 that came off the doner bike is too loose on the thorn. ...
I have a campag mirage front.
First post - nice forum. I hope to be riding my new steed soon and will try not to ask such drivel in the meantime

Ah, I see that campag don't make that size and I'd need a shim -apparently Shimano provide with their derailleurs - or I'll have to buy a braze on and an adapter
Bit of a pain

Welcome, MBN. There are no stupid questions, just stupid ways of wrecking components, generally arising from not asking the question! This is a nice forum: no one will sneer at you for asking a question.

Not sure if this would be the right size for you. I needed a shim for front derailleur on a different bike. In my case, the shim was needed because I used a derailleur that came off an Aluminum frame bike with larger diameter tubing.
I found that the shim I needed was exactly the same thickness as a shim that came with a stem for a 1 1/8 inch steerer tube, the shim was to convert that stem to a 1 inch steerer. With a hack saw I made it the right size and put in the second slit so that it was in two pieces.
