As per the thread title can anyone confirm this for me as the choices are 68mm and 70mm for the ultegra bb http://www.chainreactioncycles.com/Mode ... elID=38998

I am not 100% how to take this measurement but think its from the inside of the cups >=< I had my calipers on this with the chainset on and am getting 68.5mm so I think I am right here but would just like confirmation of someone who knows about this sort of thing as this will be a 1st for me if I change it (i will get the tool also)

Thanks,

Martin
You just gotta peddle

  • 70mm are for Italian thread, so I would put money on it being the English 68mm version

  • Thanks Stokey. I may just pull the trigger and get one ordered as I can always return it and I am 99% I am right on the 68mm
