I am days out from my shoulder replacement the humerous/ball and already I miss my bike. If I am luckey I will get to ride in 4 months. I had a wreck 4 years ago on my fixed gear and after all kinds of doctors shoulder manipulation and therapy I found out my bone was dead. The good news is I can read this forum and I now have a piece of titanium in me/ball lol. So instead of riding titanium I will take the titanium for a ride!
