i don't think the sturmey archer's work like the older bendix. have to go back and re-research it for sure, but i think the sturmey's are like an auto 2 speed that shifts up once you're going so fast, and the older bendix' are a kick back you shift back and forth bettween regardless of speed. i'd like to pick up a bendix for a k.i.s.s. type cruiser, but i can never catch a cheap enough deal.
