to learn that the rear wheel in this new old bike I’m fixing up has a “Sturmey-Archer S3C Tricoaster” three-speed coaster hub, which is to say that it actually has a goofy little transmission surrounding the rear axle which is responsible for both shifting and braking. Doing both of these in the same hub is perhaps a little overambitious, which is apparently why it took Sturmey-Archer five tries to make one that could do both without having the brake fail if you shifted bad. But having the shifter and brake in the hub does make it safer to ride in wet and icy conditions, so who’s really to say if 1960s British bicycle engineering was good or bad?
