Bastard stepchild is right, but the frame is a Windsor Pro Track and if you want to flip it you have just what the market wants right now...vintage track iron. Those components make the weirdest gruppo I have ever seen, and I've assembled a lot of weird ones in my day. Funny that those Mexicans drilled a track frame for both F&R brakes, but it was funny times. Nice bike, and with that Campy Pista crank it's worth some big $$!
