SS is fun and sexy. BUT!! All of you had better start thinking about joint preservation NOW, that is if you want to stave off a TKO! And I am not talking about boxing. If you are on a track, that is different. I watched some pathetic old fart that thought he was cool blowing out his knees on a little switch back the other day. He was about 50, 170 lbs, he will not cheat physics! Geared bikes really was a smart invention.
