I wanted to get a wheel built with a single speed coaster brake. I asked the mechanic to use a Sturmey Archer hub, which I could have sworn existed even as recently as several months ago. But he tells me there is no SA single speed coaster hub listed in any of the dealer catalogs. Does anybody know what happened? Did they recently discontinue it or was I delusional in imagining it existed? Is Shimano really the only option for a single speed coasterbrake hub nowadays?..
