this forum? If so, I'm looking for free advice. I've been riding 80-90% single speed only... mtn and road for about 5 years. I only use my geared bikes for rides over 3 hours, and with 2 kids, that is not too often. However, over the last 2 months or so, SS rides have left me with huge amounts of pain in my hip and low back. I haven't changed anything on my bikes, so It's not rider position. I've gone to the bone cracker and my SI joint has been so swollen he has been unable to move it back into place. The only thing that helps is a week off the bike and copious amounts of advil. I always assumed knee pain would put me back to gears one day, but I'm only 36, I thought that would happen 10 - 20 years from now. Anyone experienced this? Know of stretches or strength building excercises that might help... Or should I just polish up the gearies and leave SS behind?
