You dudes are right, the reason that bike brought the cash was because it had the aero speeds, the hutch prices have gone nutty here lately, on everything from pedals to the valve caps etc. I have seen the aerospeeds bring 2k just by themselves, I have a few bmx bikes myself, anything from the 80's anymore is commanding big bucks, such as skateboard decks, bmx bikes etc. If you have noticed they decorate the TGI friday's restaurants with bikes and such memorbilia from the 80's, so there is a guy that buys just for them on ebay and spends ridiculous amounts on things just to bolt it to some restaurant wall. As far as the GT'S go, the pro performers and pro freestyle tours etc always bring more, especially if they have the mallet stems, and the 3 piece gt cranks. Bmx parts are the same as trikes, the higher end stuff back in the day brought more money, that meant, 3 piece cranks, full cromoly frame, usually rear .990 brake posts intead of side pull calipers, etc. I have a chrome 89 pro freestyle tour frame I am trying to build up now, slowly assembling the parts, about all I have left that I really need is 48 spoke wheels.
