Sorry, difficult for me to take the crank off. I will do pics with the next service. For the time I am happy that is properly assembled. Yes, using Hollowtech cranks.
I have in the front and back standard BSA bottom bracket with 68mm. Gates requirement for using Gates belt with 69 sprockets is:
DIM A (69T SPROCKETS); NOMINAL CENTER TO CENTER DISTANCE 720.69MM (712.69MM FOR BELT INSTALLATION, 722.69MM FOR PROPER BELT TENSIONING.
The boom tube length was set to the proper tensioning length of 722.7mm. I was told by builder they can work it as accurate as less then 1mm. The belt extension over time is very very little and the eccentric bottom bracket should handle this. Time will tell but I am confident.
