trouble inserting them into the ends of my handlebars. The bar in
question is an SR Sakae Custom Anatomic. The shifters are ultegra
8-speed. I can squeeze the shifter in a but, but don't seem to be able
to get them in more than about 1/3 of the way. Is there a trick? Do I
need to ream or file something? Should I just smack it with a mallet?
TIA,

I had exactly the same problem with a Modolo bar some eight or nine
years ago. The tubing seemed to be just a bit too thick to allow
mounting the shifters--and believe me, it's not easy to remove material
from the expander--I tried.
My procedure (not recommended, just for information) was as follows:
I found a wood-boring drill bit that was "just" too big to fit into the
handlebar end. Very carefully, I used this to ream the end of the bar
to about 1" in depth. Once I had done this, I was able to fit the
Shimano bar-con into the bar.
It worked well for a few thousand miles--I never had any troubles at
all. I think that's because (at least with my riding style) there
wasn't a whole lot of stress just above the bar-cons. Clearly, if you
ride with your hands on the ends a lot, it's not a good idea.
I'm willing to try this. You wouldn't by chance remember what size
drill bit this was? My handlebars are labeled "Modolo" as well as SR,
and I'm thinking what worked for you would work for me. Barring that,
what do you think of the idea of using a tapered hand reamer?

Could well be the same bars...I *think* mine had a sleeve at the
center, with the Modolo script in black on one side and the model
number on the other. Been too long :-)
Alas, I don't recall the size of the bit, but it was a standard
non-metric of the kind you get in a Sears Craftsman set. A little
experimentation should show you the one you need--maybe try drilling
into a 2x4 and see what is the smallest bit that would allow you to
(just) slide in the shifter (with the expander fully narrowed, of
course).
I think a *tapered* reamer would be a mistake, because by the time you
get enough *length* reamed, you'd be cutting too far into the bars by
the opening. What you need is a *cylindrical* reamer of some sort (a
hone?) rather than a tapered one. I'm sure these exist...it's just
that when I did this O So Long Ago, I was near-broke and had to use
what I had in the toolbox. Ask your LBS if they have anything like
this...I seem to recall that there's a special tool for widening seat
tubes, so they just might have something similar to that.
If you have the patience, I suppose careful wet-sanding might be a way
to remove just enough material...Hmm. Or a Dremel tool set up with a
grinding stone? Handlebar aluminum is pretty soft, IIRC.
