Interesting info, Scott.
I had a 1960 Schwinn Tornado that was the cheapest bike in their lineup, but it rode like a champ.
I always figured, that Komet hub had to be one of the least expensive hubs available at the time to be spec'd on that bike, but it was one of the smoothest rolling hubs I've ever ridden.
The whole bike only cost $27.00 dollars brand new, so that hub must have only been a couple of bucks at the most.
The Komet would get my vote, except I've had way more experience with the tried and true New Departure, and the replacement parts are plentiful.
So for me, It's the New Departure Model D all the way. plus you can convert to a two or triple speed if you like. How can you beat that ?
