One of the simpler "ballpark" tests is to sit on the seat, put the heel of one foot on the corresponding pedal, and push the pedal to the six o'clock position. Your leg should be almost straight or even straight, but without having to move your pelvis down on that side. Check the other leg.

Then when you clip in or put the ball of the foot on the pedal, your leg should have a bend in it. I've heard of an angle at the knee of around 130 degrees to be ideal.

Do you pedal with a pronounced downward pointing of the toes?
