• Generally speaking, if you switch a JIS crankset for another JIS crankset, will your chainline be unaffected? Or do different cranksets sit differently on the taper itself? Thinking of replacing my Lasco CF12 for a FK55 CNC, but not sure whether this will affect my chainline and it's an £80 experiment. If it did affect chainline, what would be there remedy? A different width BB?
