Would someone by any chance know how to remove a hubbub adapter from a handlebar?

Just in case, the hubbub is this:

just like a barcon shifter. stick an allen wrench in the end and loosen the nut. it should pull off.

It's probably in there really tight, I have to crank my to keep it from slipping. Unlike a SunTour barcon, the hubbub has standard threads, turn it counter-clockwise to remove.

The bar end is fitted with a hollow bolt, Right hand threaded,
that is standard thread.
but you are on the opposite end from the head of this bolt ..
it faces forward.
so the perspective is flipped , loosen is clockwise

As I recall, I had to "jam" the hubbub into the bar end and twist it clockwise or counter-clockwise. I've attached a shifter and turned it counter-clockwise to no avail.

Well, it's a fine point but Sun Tour and Shimano barend shifters are attached with standard right-hand threaded bolts. The problem from the mechanics perspective is that you are turning the expansion bolt from the end opposite the head so it appears to loosen and tighten the "wrong way". It's like you were installing a quill stem from under the fork crown.

Its all relative , twisting the HubBub thing clock wise, bolt held in place
or holding the thing fixed and turning the bolt CCW .

SAT tests had things to figure out mechanical things , wonder if they still do those tests.

Maybe some enterprising company will come up with a road bar ,
just reduce the last few inches of on end down to 22.2mm

Over the years, I saw some Scott and Modolo in the 'drop-in style',
where the drops bend back to the center , those would be perfect to do that ..

If you are really having trouble you could always call the shop that create it.
