OK, the chainline is 47.5, which could be easily determined from the two numbers I provided = 73/2+11= 47.5.
I am still not sure if the BB UN55 73x122 and the SHIMANO M361 Hybrid Crankset will give me this chainline.
Yes, I looked at https://www.sheldonbrown.com/bbsize.html adn tried to find the tech specs for this BB and Crankset, but still not sure.
Could please anyone confirm if this combo will work?
