joejack951, thanks for the info. The 105 crankset is on the heavy side, so it would be a good time for an upgrade. I prefer the look of SRAM over the Ultegra or Dura-Ace, and it looks like some nice weight savings can be found with the swap too. If I purchase a SRAM crank with bottom bracket & bearings, will I still need new cups?

Im a 951 fan too, have an '86.
