I'm replacing the trigger shifter on a bike with an SA 3-speed, and I've got an issue with the cable fitting the shifter. The old shifter is one of the original UK-made ones, but the replacement is one of the new Taiwanese ones. The Sturmey cable I was using fitted the original fine, but the slot into which the cable fits on the mechanism of the new trigger seems to be narrower than the one on the old trigger, to the point that the cable won't go in. Have the cables gotten narrower with time, or am I missing something?
Thanks in advance
