shifting under power (especially with rudimentary '40s dérailleur) is better with longer chain, most noticeable on a tandem where it's very tricky to synchronise easing up on the pedals to change gear.

unfortunately this one benefit is a bit outweighed by the 4-foot chain dancing about like a motherfucker every time you shift/hit a pothole
