the most significant downside to this bike is probably that dicks will try to make you feel bad for riding one. This is important for some people, not to have other people think poorly of them for riding a less expensive bike.
last time I looked the welds on the bianchi pista weren't that hot but hey, we'll let it go on a bianchi...
like hammye said, just replace stuff as it goes bad, $370 ain't a bad starting price if your buying new.
