Hello, I recently did a about a 100 mile stent on the Katy Trail out here in Missouri and was riding a new bike I had just picked up the week before and about 20 miles into the ride started feeling me knees hurting. I figured it was nothing so we continued on our way to the destination. My knees were hurting so bad by night time that I could barely pedal anymore. I was dreading the ride back the following day and during that ride I had to seriously quit the ride and wait for my riding buddy to finish the ride and bring back the car because I was in so much pain. I have never exprerience this kind of joint pain before ever and have ridden those types of rides in the past on different bikes and did not have that problem. I was told that I should have had the bike fitted so I have since then had the bike fitted to me and still a month later my knees still at times hurt even when I am not riding. They seem to be very slowly getting better but not back to normal. I have done small trail rides since and have gotton my knees flared a time or two but not as severe. Ok my question is has anyone ever experienced this pain and what should I do about it. My bike seems very comfortable and measures up well so I don't see how that could still be the problem. Any suggestions would be very appreciated. Thank you!!
