I've been told that with this setup, I shouldn't have/need any shims, but compared to my BB30 Caad10 with the wavy washers etc, that surprises me.
Hollowtech 2 cranks are a different design. They self adjust for frame tolerances through the NDS preload bolt and sliding NDS arm. They will still work that way when using adapter cups in a BB30 (ish) frame.
The turbo will bring out every creak, ping and whistle in a bike. Leave it alone and put some headphones on :)
Assume you've stripped and cleaned the cranks and all the adapter bits?

Bottom bracket issues to sort out...
It has ceramicspeed bearings and the non drive side sounds a bit gritty and I can hear clicking. Hadn't noticed on the road, but on the turbo, the noise is driving me mad.
Currently I believe it is Specialized OSBB 61mm with 2 3.5mm Wheel MFG spacers to 68mm, with Wheel MFG spacers for Shimano, so a bit of a mess (though apparently standard for Specialized carbon frames with Shimano)

I'll probably end up getting a Praxisworks conversion BB, but want to try servicing the bearings first as they cost a fortune, which hopefully will sort out the grit, but maybe not the clicking.
1) Empty can/cans of degreaser to clear the bearings in situ, regrease and hope this sorts the problem
2) Remove bearings, disassemble and put in my ultrasonic cleaner with solvent, reassemble, grease, reinstall. I don't have a bearing remover or press, so will need bikeshop assistance.
3) Give up - Replace with Praxis BB
Any tips or help would be gratefully received!
Other than that, watching out for good deals of Duraace 9000 gearset, when people upgrade to 9100, and have some Aerofly handlebars and white camo bar tape to put on when I do.
