Just checked on my laptop, the DA BB is 7700 Road and not 7710 Track.
Have you used both BB with the Shimano Dura Ace 7710 Track Crankset?
I just want to cross check the compatibility as I understand there are various Octalink versions which are not intercompatible and affect the chainline.
DA BB 7710 is the track NJS version with sealed bearings and steel cups, the 7700 road has got needle and ball bearings, alloy cups I believe and its not sealed, but both have got 109.5mm axle length.
These are Octalink V1 with the shallow spline grooves.
Thank you.

Thanks again & sorry to be a pain!
