I did some research myself on seat position, specifically fore and aft positions. I believe if this is improperly set it can cause knee pain.

I moved mine back about 20mm and the front intermintant knee pain I had has subsided.

I learned that we should not use the seats fore & aft position to alter reach. We can do that with a different stem. Seat position is best set relative to the pedals.

I set the seat height so I have just a slight bend in the knee with normal riding and can fully extended it if I try. I have a suspension seat post, and must take the 3/8" drop or so into account when measuring.
