http://www.bikebrothers.co.uk/ih_grubb.htm Ian Hibell used a 31 on the rear he said it ran on the ragged edge of good performance. I never tried this with a Campagnolo but on Shimano and Sun Tour you can use a larger gear by pulling the derailer back either by tying the cable to a fender strut or I saw one person use a spring.
