>>1951727well you can mount a shifter anywhere in theory, but don't you want your it next to the grips? reaching for an extended bar seems rather inconvenient. since it can't slide pas the bend (blue) i could mount it on the other end (red) but then i'd lose the "hoods" position.
i obviously wouldn't get the actual surly steel one, just some aliexpress aluminium crap.
>>1951599alfine does use trigger shifters usually, it's the nexus that almost always uses a grip shift. apparently they're interchangeable, but it's probably not worth the effort of buying a new one and swapping it rather than just frankensteining a grip shift on to a corner bar.
