I want to use a Centaur carbon crank. I have a Centaur and a Chorus square taper cartridge BB from a few years ago. The spindle length is a bit different. Will the chainline be bad enough to matter if I mix models (use the Chorus BB & Centaur crank) ? Do I need to use the Centaur BB with the Centaur crank ? I don't know the year these were made, if that makes a difference.
