In preparing for clipless pedals, I started riding this week with the ball of my foot over the center of the pedal, where it will be with clipless, instead of my foot being further forward on the pedal, as it has been in the past inside the toe cage I've used. I know I may need to adjust my seat height but is this normal to feel pain in and around the knees until I get used to the new position? I feel like I'm putting more strain on my knees and upper quads than I did with my foot slightly more forward on the pedal. Any suggestions?
