Ok, seriously, I've been a mechanic for years and I thought this would be a simple matter of looking up the measurements of each component and making the necessary compensation in spindle length, but what the hell am I gonna do here...? What the hell interface am I even supposed to use for superbes? JIS? Campy? Is the Ellipse Chainline boogeyman even real? It seems like every time a question like this is asked, everyone just starts shouting contradictory bull. please help.
