I'm in my 3rd year of road cycling and have just started having this weird knee pain. I'm pretty sure it is from changing my seat. Last year I would have this weird soreness in the groin area where the leg meets the groin. I noticed I only seemed to get it from riding outside. I have a different bike for my trainer inside. So I put the same seat on my outdoor bike as I have on my trainer bike and now I haven't had that problem. But as I'm picking up my miles outside my knees are starting to get weird pain. Sometimes it's while I'm riding, sometimes its just randomly through the day. One knee or the other will have a little pain in the front and sort of to the outer side of the knee. So it is always on the outside area but towards the front. It seems to be moving back and forth between both knees. One day it will be the right and the next the left. Pain/discomfort might last for an hour or a few then goes away. It is more noticeable on stairs. Have only experienced it on longer rides, usually I'll just get up to walk and suddenly feel it. I'm pretty sure it has something to do with my fit changing with the new seat as I had no issues last year and had no issues through the winter just using the trainer bike. I put my seat back slightly, but don't think that fixed the issue. Last time I had knee pain it was in the back of the knee and lowering seat fixed that. Any suggestions for how I should move forward? From what I read it sound like moving seat up/back is the thing to do. With the new seat I'm not sure how much room I have to move up as I'm sure it changed my fit. I'm currently taking a couple days rest from riding hoping. Usually I ride 5-6 days a week.
