I theoretically have a 73mm bb shell going back to a 142 space disc brake frame which mandates a 51mm chainline. I want to run a square taper bb with a SPA narrow wide crankset. What bb length do I need to achieve the 51mm chainline?!?!?
Zicral rings are CNC machined 7075 T6 in a polished black finish with laser engraving to complement the cranks.
Recommended bottom bracket: First Components DX-30 110mmDo you know what chainline they're aiming for with the 110mm? You should be able to adjust to 51mm from that once you know.
