This is my main source of transportation, an old Nishiki ten-speed that I picked up for twenty bucks at a local thrift store. From the late seventies/early eighties, or at least that's what a random cyclist I chatted with told me. It did time as a single-speed for a few months but has been fixed for the last year.
Parts that I added:
El Toro bullhorns
Shimano SLR brake lever
Shorter SR stem - from my junkpile
Sakae pedals and toe clips/straps
Homemade leather handlebar bag and tool-bag under the saddle
Brooks B-17 green saddle rear rack - also from the junkpile
Specialized Armadillo tires - bulletproof, not a single flat yet
Surly New fixed/fixed rear hub
Generic track cog and lockring
Zefal plastic fenders - for the occasional Texas rainstorm
