total fixed-gear newb here as mtnbiking has been my thing for 15 years, but i got the bianchi pista in late march - $450 - and love it for me. i use it as a training tool and try to do two 30 mile days on the streets of hilly alpharetta (atlanta) each week. longest ride thus far was 62 miles on the silver comet - a local rails-to-trails which is pretty flat. on the hilly streets my longest is ~40 miles.
no experience on the track, but that's what the bike is billed for on paper.
