Should crank be centered?
Hello all,
I am trying to build a 1985 Fuji Sagres with a Sugino Maxy crank (which is not original, I'm replacing the original crank). I currently have a 118mm UN55 bottom bracket installed.
The drive side crank is 40.5mm from the seat tube, the non-drive side is 47.5mm from the seat tube, and the inner 40t chain ring clears the chain stay by less than a millimeter.
What's going on? How should the crank be positioned, why is it so off center, and what do I need to do to fix it?
