I would like to move the chain out a bit since it's rubbing the left leg of the V-strut on the pivot arm when the chain is on the largest rear cog. The width of the BB on the bike now is 116mm. I'd rather not spend a lot of money, just looking for something sturdy and well made that will last. No need to shave grams.
I use a Shimano Dura Ace 7800 crankset with the hollowtech bottom bracket, it weighs about half what the original parts do, and is easy to install. 105 or Ultegra work just as well, and are still quite light. I have no issues with rubbing using an 11 speed rear sprocket.
