LeMond's preference for shallow seat tubes was the key to relieving knee pain for me. When that book first came out I was racing and suffering from serious knee pain. I read the book, set the saddle to his suggestions and the 20 years since has been blissfully pain free.

Yes, top tubes of his bikes are too long for me, but love 72 degree seat angles! Allows me to locate my knees behind the pedal spindle.
