I've been doing mountain riding for the last three years exclusively, riding with my Sidis and SPDs. I've never had a problem with knee pain.
Recently, I bought a road bike and took a couple of really long, excruciating rides. I think I probably overdid things for those couple of rides, because I started to develop some knee pain on the front inside of my knee (on the inside front of my kneecap, extending down below the kneecap). My new bike has SPDs and I'm using the same shoes, so I'm wondering what causes the pain. Is it because I went too far without being in the proper shape (my legs and knees aren't very strong at the moment)? Something about the new bike? I'm riding a compact double and a pretty 12-25 cassette in the back. Seat height gets almost full extension on my legs.
Anyone with experience with this kind of knee pain feel free to chime in? Should I stay off it for a while? Take some yoga and do strengthening exercises? Go to a sports doc?
Never had knee pain before and I'm paranoid it's gonna put a damper on my cycling, especially with the excitement over my new bike. So I'm at a loss about what to do to correct the problem.
