The special trigger controls designed for the ASC hub are even rarer than the hubs, so I took this 1950s "3 or 4 speed" trigger apart and ground off part of the escapement cam to make it work properly with the ASC. You can see where I ground away the "2nd gear" notch in this image.
The trigger was meant to be mounted on a curved section of a handlebar, so I needed to shim up one end of it to clear the straight section of the Scott AT3. I used the handiest thing around, a knurled nut from a Presta valve.
