According to my instruction manual minimum sprocket size is 13 teeth for my long cage derailleur (Campagnolo Record 10 speed). I would like to run it with 12. Is there any reason that would not work?

    It's probably due to the amount of 'wrap' of chain around the sprocket due to the angle of the parallelogram - I would try it first - expect it's more due to accelerated chain wear than anything else
    Make mine an Italian, with Campagnolo on the side..
