自锁片前后调到大拇指骨为脚踏着力点， 脚踏水平时将座位前后调到小腿垂直，膝盖不超过脚踏着力点。
附一段文字，希望有所帮助：
For & Aft Positioning - For fore/aft, there are many schools of thought about exactly where the cleat should be positioned and there is no definitive answer. The old rule was that the cleat should be positioned such that the ball of your foot is centered over the pedal. New thought has it either slightly in front or behind the ball of the foot depending on shoe size. The main point is to experiment with your cleat position, making minor changes each time. I would recommend that you invest in a visit to a really good bike fit person. Incorrectly placed cleats can lead to horrific pain and life long injury. But a good fit set you up with a more efficient pedal stroke and a future of cycling enjoyment. Go to our page about Bike Fit
Seat Fore/Aft Position
Adjustment: Make sure the bike is level on the trainer. Then hop on and pedal a bit to warm up the muscles. Stop pedaling with one foot at three o’clock. Have your assistant level the crank arm and the pedal. Maintain that position while your helper holds a plumb line (a thread with a nut on the end works fine) against the indentation just beneath the bone that’s below your kneecap. Adjust the seat fore and aft on the rails until the plumb line bisects the pedal axle. Make sure your knee is not in front of the center of the pedal when the forward leg is at 3 o'clock.
How to do it: Loosen the same bolt used to angle the seat (see Seat Angle section).
