So the 3mm would make a big difference? I am actually in the process of perfecting the shifting in the front and thats why I was curious about the bb measurements.

I just got rid of the stock FSA chaingrings and replaced them with SRAM which has been a dream in itself. The front is now shifting smoothly but the Platinum Pro BB is getting noisy and since the BB are so cheap on eBAY I wa considering either the American Classic or Crank Brothers but only see good deals on the 113 variety.

Is there a way to tell what size my bike is made to take? though I assume it is 110 but the stock BB has long since been gone. I have been fighting the full upgrade to a GXP and trying to make the best of the ISIS setup.

Any advice would be appreciated.Thanks
