We've covered this issue before. Campy made any length in tandem cranks, but you had to order it. My other set is 165 / 167.5!!
This is a factory-made tandem set - the arms with the reverse threading have the "S" and "D" stamped in them - how could you tap a reverse thread of the same diameter into something BTW?
