I've been having some knee pain so I decided to do a "sore knees" search here in BF and I read a lot of good stuff. Before I get into that I should give a little description of myself and my bike: I'm 42 (for about one more month), weigh around 300 lbs., and I am back on a bike after an almost 20-year hiatus. Before getting the bike my activity level was almost nil. My bike is a dept. store (pause for the collective gasp!) Schwinn hybrid with suspension forks and a suspension seat post. (Please ignore the necessary evil parked behind the bike):
I've been riding my bike quite regularly since its purchase and have occasionally had some knee pain, but I figured it would just go away with time as did the butt pain. The knee pain has come and gone, switching from one leg to the other, but I never really noticed any knee pain at all before I started biking. At first my bike rides were all recreational and averaged about 10-15 km or 6-9 miles. Since September I've been back at school and my cycling has been almost exclusively commuting which is only a 6 km, or about 4 mile round trip. I took the above picture on a day when I wasn't at school and I had just taken the bike on a 15 km ride (I had to test out my new studded tires and fenders). That was Wednesday of last week. Since then my right knee has been constantly sore and I really notice it when I ride.
So on with my story: I read a lot of tips about proper fit (which came as no surprise), high cadence/low torque, proper cleat/shoe fit (n/a with my platform pedals), and one tip I hadn't thought of: nix the suspension seat post. In retrospect this was one of those "D'oh!" moments that should be a no-brainer. I plan to change to a rigid seat post at my earliest convenience and I was curious to see if anyone here has had a similar experience and if so, did you find that changing to a rigid seat post helped? Any other advice (other than going to see my doctor - that I will do if the pain persists) would be greatly appreciated.
