Well my current bar is 22.2mm OD and a 18MM ID at the end, which is only 0.5mm too small for my end plug lever. Since this is a pretty cheap bar, I'm inclined to think that there are many MTB bars in which the plug should fit because I'm only short half a mm and, as noted by tatfiend, lighter bars should have a bigger ID.
So I think it's a reasonable guess to assume that my end plug levers would fit most quality 22.2mm OD aluminum bars. Therefore, my current question is if I can expect a carbon bar of the same OD to have a thinner wall than aluminum or not. I'm inclined to think not because my impression is that carbon walls are usually thicker, but if anyone has reason to think otherwise then please advise.

I do not recall seeing 26.0mm MTB bars though they may exist.
Nitto does offer 25.4mm stem clamp area drop bars with 23.8mm main diameter for use with road levers.
Willing to bet that there is little or no standardization of bar internal diameters regardless of material. As I mentioned both my Civia Hyland and Swobo Dixon aluminum bars are 22.2mm outside diameter in the controls clamping area but are very different internal diameters at the end of the bars. The Civia bars use much thinner wall aluminum.
Hmmm, my current bar also has 0 degrees bend (it's just a straight tapered tube). I'd also like to keep that shape, but I'm having difficulty locating carbon bars without bend (only aluminum or steel).
So perhaps I'd be better off finding a wide drop bar and cutting off the drops. I don't need a bar more than 450mm wide or so. Do you forsee any problems with this plan?
