I am looking at a Bianchi Volpe on Craigslist that appears to be 49 cm (I asked the seller to measure it) but am not entirely sure that it wouldn't be too big. The bike is a good 2 hours away from where I live so I don't want to make the trip without being pretty confident that it will work. I am 5'2.5" with 30" inseam, longish arms. Anyone else ride one of these and have any insight into the sizing? Here's the ad: http://worcester.craigslist.org/bik/4156491884.html
