I'm looking to build a new rear wheel for my single speed and I wanted to try out a coaster brake. I'm worried about the supposed extra drag that most coaster brakes have over a normal fixed or free hub. I've rebuilt a couple old Bendixes, both US and Mexican built, but they were too draggy for my liking.
Has anyone in SSFG used a coaster brake on their SS or fixie? If so, what kind, and how easily does it spin? My current dream hubs would be an old Morrow, New Departure, F & S Torpedo, Velosteel, or, to get really crazy, the two-speed kickbacks, either the Bendix Yellowband or the F & S Torpedo Duomatic. These are all older hubs, but I've heard that newer hubs are lower quality, either performance or durability. Anyone have experience with both older coaster brakes and the newer stuff by shimano and KT?
I've read through all of Jimv's posts but I never saw anyone rate the different brands based on hub drag.
