I've had problems with sore knees after 20 miles or so. It never seemed to get worse, but it wasn't getting any better. After a 50 mile ride they would stay sore so that after coming home I would feel it walking up some stairs.
The last ride I stopped after about 22 miles and raised my seat post a bit. Maybe half an inch, maybe a touch more. I was just going by feel. I got back on the bike and my knee pain was gone. Completely. Well, that's all good, but I'm afraid I might have my seat a little too high now. I'm not sure. I only had another 15 miles left after the adjustment. It was strange how such a small amount made everything so different. Some different muscles in my legs and hip area were a little sore that never were before. Not in a bad way, just in a work-out kind of way. My spin felt very different.
So I guess for my knees, I need to have the seat as high as possible without other problems occurring. It's obvious to me now that very small amounts make very large differences and I have very little "wiggle rooom" when it comes to seat height.
So I'm asking for some suggestions on how to monitor whether my seat is too high or not. I know it was too low, so I'm in the ball park. I'm going to mark where the seat is now and make a few more 3mm apart from each other (got that from some bike site) so I can always find where I am right now and lower it (if needed) in very precise, measured amounts. I don't have anyone else to bike with, so I'm on my own. How can I tell if my hips are rocking? Are there any specific kinds of tests I can do while I'm out?
Thanks for any help.
