moustache handlebar and bar end shifters?

How would I know whether a moustache handlebar could accept Shimano bar end shifters? I saw some bars on ebay that had an outside diameter of 23.8mm however the listing said that it cannot accept bar end shifters. Other than diameter, what do I need to consider to ensure that I can install bar end shifters?

Any insight would be appreciated.

23.8mm refers to the outter diameter of the handlebars (everywhere except where the stem clamps) and is pretty standard for "road" bars.

However, the inner diameter can vary from bar to bar. Generally, bar-end shifters require the inner diameter at the ends to be within a particular range. Chances are the bars you're looking at have too small of an inner diameter.

Makes sense. Would you happen to know the inside diameter that will accept Shimano bar-end shifters?

I don't know a whole lot about the specifics of bar-end shifters, but according to: http://bike.shimano.com/media/techdo...9830605258.PDF , the Dura Ace SL-BS78 requires an inner diameter of 19.0 - 22.0mm.

19mm = about 0.748 inches. That sounds about right.

makeinu,
I used a .75" hole saw to drill/mill out the bar ends of some trekking bars (aluminum). Had to go about 1.5" deep. The difference between the OD and .75" left sufficient material to make the mod.

Find out what the OD at your bar ends is. If the difference between OD and .75" is large enough, you can try machining the ID to .75". Or you can take it to a machine shop and let the professionals do the work. Either way if you can make the ID reach .75" (or 19mm - 22mm), you can install the bar end shifters.

At least if we are talking about Nitto bars, they fit.

Yep, otherwise you're going to be doing a lot of research. There's not a whole lot out there. And it depends on what you're planning on using for brake levers. Road levers and barcons = Nitto. If, as on my wife's bike, you want barcons and mtb levers, then you're looking at Soma's Sparrow bar. That was about all I found.

And be advised that all moustache bars are not created equal. If you want to ride the curves, the Nitto bar (or Nashbar's knockoff) is your best option. If you just want an upright, swept-back riding position, then you have other options. While I ended up with the Sparrow, I'm not particularly happy with its profile (the bar ends stick out too much, as opposed to winding up parallel to the top tube). This makes it really wide with the barcons in there. But my wife likes it, so end of story.

Oh, and what may be advertised as Nitto's moustache bar may not, in fact, be their actual moustache bar, as I experienced with JensonUSA.

If you want more detail, PM me.

I have a Nitto moustache handlebar with Shimano bar-end shifters (the stock shifters that came with the Surly LHT). The Nitto moustache bars do accept the Shimano shifters... don't know if the other brands do or not. I love the way I can shift from the ends of the bar without having to remove my hands, unless I want to.

If it's the Origin8's they do not fit unless you modify( grind/cut/sand the inside).

This shows how to do it right:

Wow, I would love to have that equipment to do it right, I would be down right dangerous. I started with a dowl rod and coarse grit sand paper. I then moved on to using a Dreml tool, with a coarse grit tubular sanding attchment. I went slow and kept an eye on it too try to keep it even. I was worried I would cause a grove or low spot that would focus the stress and cause a failure. Then I thought -Hey its not like all my weight will be at the last 1.5 inch of the bar, so I trudged on. About an hour into it, I relized that I should have just used thumb shifters or bought a more expensive bar that needed no modification.

Nitto-Silver, only in aluminium. They take bar end shifters, 26 clamping area
Nashbar-silver, only in steel, take bar end shifters as well, 25.4 clamping area
Origin8-Aluminium. but on black, don't know about bar end shifters, 26
Soma Sparrow-silver or black, aluminium, takes bar end shifters, but not really a mustache bar.

I would be surprised if any modern moustache bars wouldn't fit standard bar-end shifters. Nitto's aluminum moustache bars work with bar-end shifters, and the steel moustache bars sold by Nashbar worked on this old commuter bike of mine.


Any bar with an external diameter of 23.8mm (standard for road bars, works with road brake levers, etc.) should be fine with most any bar-end shifter. This is different than the handlebar-clamp diameter of 25.4mm or 26mm.

I dig those bars. Have you tried turning them over for a more upright position? I'm thinking about that for an old bike I'm eyeing.

I dig your left side "bar-end shifter" by the way, what vintage is it.

I've never tried flipping them because it means the hands-forward (on the curves) position becomes a really weird angle for your wrists - but if you're only going to have hands on the sides (straight part) then it should work okay.

Quite vintage. France, 2001, to be exact
Generally, wine corks work nicely to plug the ends of handlebars.

The problem is in terminology. Many sites label bars "moustache". Many of these are not, if you're going by the Bridgestone/Nitto profile. Many moustache profile bars available are not called "moustache". The Soma Sparrow is definitely not; bought for my wife and don't like it much. Sticks out too far, not enough curve.

sparrow

The sparrow isn't really a mustache bar, its closer to a north road. It's also pretty narrow, but then again, i run the 56 cm Nashbar Mustache bars.

I haven't seen it in person, but the '3 speed' bar looks more mustachey than the sparrow.

I have the North Road Nittos (also sold as "three speed" in places) on my rain bike - not enough breadth in the curve to ride there, as on the actual moustache bar. They're really only usable at the grips.
