So something just ain't right and wondering if you all might have some insight. Particulars:

Shell width: 70mm
Threads: Italian
Crank arms: SR Suntour Superbe road double. Odd duck that differs from original Suntour. I've emailed them but nothing thus far.
Current BB: Shimano BB-UN55 70x107mm square taper.
Taper? Current BB is square. Not sure on arms although it looks like they're "seating" fine.

Any suggestions gang?
