I am changing out my crankset (Ultegra). While I am at it I am considering upgrading my bottom bracket (105 Octalink) to an Ultegra or Dura-Ace. I know that I am getting into the opinion area here, but what are the real benefits of the Dura-Ace over the Ultegra bottom bracket? I am not racing or competing, just enjoying riding hard for a 100 miles per week. Any pros or cons for me in this respect?
