Bike fit / correct riding position

Unless you're trying for TT performance gains, in which case adaptation to uncomfortable positions is basically mandatory at the top end of the field.

Who says that they need be uncomfortable! What "looks" aero is not always aero. A friend of mine developed an experimental testing bicycle where the frame angles, lengths, saddle height etc. were computer controlled and adjustible to fractions of a mm. His testing was not limited to wind tunnels. At the "top end of the field" is, however, not just hard science but also bunk science, voodoo and psychology. If riders believe that have a competitive advantage they will often deliver performance that would indicate a competitive advantage. The placebo effect is alive and well in the Peleton. Can you spell ceramic bearings--- I think my friends and I were the first to introduce them to bicycles (our tests showed a gain of about 1/4% @ norminal power output of an elite rider)? If a rider thinks they need to be low then...
