The other concern I have about the 105 is durability. Will an Ultegra or Dura Ace have greater longevity?My experience is that the wear differences are minor; and certainly not commensurate with the price differential. You are mainly paying for decreased weight, increased stiffness, sometimes better performance, and cool factor.
