Bar end shifters

Will 9 speed Dura Ace bar end shifters fit a 7/8" diameter handlebar ?

They'll fit in some better quality steel bars, also titanium bars, but will definitely not fit in
aluminum bars, because aluminum requires a thicker wall to provide adequate strength.

The outside diameter of the expander plug is 19 mm.

Once (a long time ago) I remember poking a 3/4" countersink (~19mm) into the end of a 7/8" aluminum
bar to make the inside diameter large enough to fit Bar-Cons. Seemed to work fine, but that bike was
not ridden by any gorillas.

I used a countersink (instead of a drill) because it tends to center in the hole and also feeds
slowly, due to different cutting edge geometry. A regular twist drill might tend to grab and ruin
the handlebar...
