I can see that nobody built bikes with the same size parts ,because they wanted to sell their whatevers......But why did they not pick a size for the stupid neck. One is 5'' long and then the next one you come to is 6 1/2 '' long....gotta Schwinn speedster that is 8'' long What were these fools thinking. I guess I should be happy that the BB cup size is pretty much standard. It looks like to me 6 1/2'' should have been a standard.
