I was curious about Simplex fitting a standard brazed on mount. Soooooo......
I pulled the gold Simplex retro friction shifter off a clamp on and tried to put it on a brazed on fitting that used to have a campy record lever.
THEY DON'T FIT AT ALL. ID on the lever was quite a bit smaller than the brazed on post. Didn't bother to try the friction bolt.
So before you try to hammer a Simplex retro on to a fitting remember that it sure looks like you need a Simplex specific braze on.
