Hey, I don't know much about bike specs and stuff like that, but I do know what parts are good and strong and stuff like that. Well I wanted to know some things about bike components, mainly frames. I've heard all this stuff about bike frames having a shorter end which makes it really easy to manual. But what else are they good for, and how do you know if the back is truly short enough to be called a shorter end frame? I don't know, they all look the same to me. But I'm not very experienced in this area, so thats why I'm asking. Thanks!
