Just took one of these around the block... Disc front, 2-speed auto coaster brake 26'er Swobo Otis . . . but the shop built it up with this SRAM auto (which it normally comes with a 3 speed)



I have to say, I would like it more if it wasn't a coaster brake, but it did feel pretty solid. I would imagine it to work like a set of ball bearings that when traveling at ~13mph would trigger the next gear. I would love to be able to change at what point it engages, but I don't know if that is possible. All-in-all if the price was the same, I'd go for it!
