I have always been fascinated as to whether tandems should have synchronised cranks or ones at 90 degrees.

I think synchronized would make starting off easier and 90° cranks make things more regular at cruising speed. There, I've just invented something, on the road pedal crank feathering

Sorry, meant 180 degrees!!!
