49cm centurion track frame. pdx craigslist and ebay for $450 'buy it now' without wheels.
god bless it. travis rode one of these in MASH. the bottom bracket shell snapped while he was riding it down a ramp. suntour dropouts, fork is drilled and there are bosses for a water bottle cage. i owned several centurion conversions and have been looking for one of their track bikes for a few years now. now that i do, it's too small.
hey this is our 100th post! and i installed a counter at the bottom of the page, too.
