Thank you.
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.
Thanks again & sorry to be a pain!

How much use have the Octalink BBs seen?
What is the spindle length?
What is the threading?
Can't see much on my mobile as the photos are small & low-res
