Bike fit / correct riding position

This is really good. A lot of his articles seem really technical and a bit scary (is my pelvis correctly aligned? Is my neurological feedback causing me to ride my bike wrong?) but the tips on setting your own saddle height seem spot on, and in fact similar to the method I've developed over a few years: basically (this works particularly well in winter), either go on a long ride or a hard ride and see which part of your leg hurts. Front of knee=saddle too low; back of knee or ankle=saddle too high. The thing about "velocity of extension of the rear of the knee" is pretty interesting.
