An good reference on the subject is Road Racing: Technique and Training by Bernard Hinault. He devotes 4 pages to crank length. The book is a bit dated, but his discussion of the bike and your position on it is very good.Originally posted by ians

You (obviously) have a bit more leverage with longer cranks, so easier to
climb.
