I built up a nice Pinarello Asolo fixed gear for my ex girlfriend before she dumped me! Luckily she paid for most of it; I just donated some parts and put it together. I doubt I'd do it again really... Its more fun to ride with guys who like to go fast. Maybe fix up an old cruiser for the boardwalk but theres not much point in putting something really nice together if you're just going to potter along.
