The wide tooth on the narrow wide 1x ring may have added a 1/2 mm or something, but still. I don't understand how this is possible.
It's not possible to "over insert" a crank into the BB bearing is it? I slide it in and give it a slap with my palm to seat it. That's all. When doing that, the 1x big ring pretty much would rub on the chainstay.
What crank are you running? I'm using a Holowgram/SISL2 & can put my little finger between a 56 and the chain stay. A lot of BB30 setups use a drive side spacer (for SISL2 it's 2.5mm) to set the chain line. Could be missing something?
