This is my current bottom bracket


But I wouldn’t be opposed to switching to an ultra torque bb, they aren’t expensive. My concern here is if an ultra torque bb and crank will line up properly.

I think I probably have enough room to set the fd up with a compact crank.



looks like a used but in good shape record compact crank or chorus compact crank would work with my current bb.
