Something I have noticed lately is some of these bikes have the seat about a mile up in the air. Now I'm in no way an expert on bike fitment , but if you have to have the seat that high ....You might have a bike frame that is too small. It could be that you are basketball player tall and there is nothing that will fit you. I have run into bikes at the swap meets that you would have to be in the 7' range to ride. With the seat all the way down I couldnt come close to touching the pedals. These old bikes can be stretched and will make a really comfortable ride for a taller person. This last schwinn I stretched is tall for me and the seat is all the way down. I'm 5'9'' ...not a midget , but you wont see me slam dunking anything. If your having a problem and having a hard time finding that 27'' seatpost ...email me and maybe I could whip you something up. :shock:
