I have a question for those of you who are knowledgeable about bike fit issues. Does knee pain from a saddle that is too low usually present itself while on the bike? Is it possible for a saddle that is too low to cause knee pain only off the bike?

I'm having knee problems for the first time in my life. My knee never hurts on the bike. It only hurts when I do lunges in fitness class - particularly side lunges. The pain is in the very front of the knee, right under the knee cap.

I know that I have tight IT bands. I've been foam rolling and stretching them regularly. I've also strengthened my adductors. I'm fastidious about my form on the lunges. While these activities have provided marginal relief from the knee pain, I have to wonder if something else is going on here - like a saddle that's too low.

FWIW, I've had a professional fit on my road bike but I don't ride it as often as I do my mountain bike. I had a "floor fit" done on the mountain bike by a very knowledgeable fitter. My body feels good on the mountain bike but now I'm wondering if the saddle height is causing off-the-bike knee pain.

Any ideas?
