I've read a few posts lately concerning bike fit and I'd like to get some clarification on a few points. I realize I will probably get ten different answers but that's OK too.

What are the "rules" for saddle to pedal relationship? I've heard a lot about the KOP method. If I run a plumb line straight down from the center if my knee, is the plumb line supposed to fall on the pedal axle? (assuming you have the pedals at the 3-9 o'clock position)

The other point: is the pedal axle supposed to be directly under the ball of your foot?

Thanks for any info you can provide. By the way, since this site gets so many bike fit posts, I thought Gregg was going to make a section just for bike fit stuff. What happened to it? I found a link to some basic bike fit posts but nothing too detailed.

This site is as comprehensive as they come. Lots of good diagrams. Read all the fit articles and you should be an expert.

The KOP position that you are asking about is only a starting point for saddle fore/aft position. After an initial setting it could take months of on-the-road experimentation to determine the optimum position that will produce the greatest power. Be prepared to buy two or three stem lengths to keep the reach the same as you experiment with saddle position. Many riders prefer a position that is further back from the neutral position to increase the ability to apply torque to the pedals for climbing.
