Thanks for the good info. I was wanting to know about the weights because I am thinking about picking up an old varsity or such bike at a thrift store and I was wondering if I would just have to live with the weight. I was hoping that I could find a frame the size that I want and then replace the parts that need replacing and have something that would fit me better than my present thrift store bike. I am wanting to try a 59 to 61 cm c to top frame and the only bike that I have seen so far weighted about 40 pounds so I decided to pass on it. I know that the cost of replacing parts adds up quickly and it probably is not going to be economical to replace very many parts unless I can just swap parts from some of my old bikes. So I will probably just keep looking for something a little lighter that is the size that I want to try out.
If anyone has a link to the thread/threads about lightening up a varsity or schwinn link me up.
