joejack, the short answer is yes and more.
BB is 68.1mm, I have also tried the activ link in an undersize bracket I have tried longer spacers I have tried precompressing the bearings before installing the crank. I'm now consider polishing out the bearing housing to allow the non fixed bearing to move more freely as looking at this ridiculous design the slightest resistance from the outer bearing shell would load and bind the unit.
