I also caught the "light" bug for my pista (oi also caught the "vodka" bug tonight).
I have a set of velocity areoheads (which are not that light) but for longer rides I slap a neuvaiton sl2 front wheel on (from my road bike) (does neuvation make a track wheel i wonder, they are awsome and really light). Nashbar carbon seatpost, Forte (perfromance(kinesis)) fork, easton stem and lighter risers, as well as dura ace cranks and ultegra BB, kmc superlight chain, dura ace front brake.


ok, i put lots of new stuff on, but it was almost all in trades on craigslist, so in the end I paid under 100 for everything (mostly for the vredstein tires, which are essential in brooklyn). it it light...eh, maybe, do i now fear locking it up anywhere....yup,

end result, pistas are fun to upgrade, and get stolen as often as escaldes
