Some easy way to attach 22.2mm bar ends to 22mm handlebar

Hi.

I believe 22.2 mm is considered a standard diameter of bike's handlebar's grip area, but I've got 2 different handlebars (which I overall like) from 2 different vendors - and both of them have grip area with diameter of 22 mm.

That tiny difference makes it hard to find barends which would attach to it. I've got 2 different bar ends which I like very much as well - and I can't fit them 'cause they are designed for 22.2 mm handlebars.

I've tried to search internets for some kind of shim or adapter (22 mm to 22.2 mm), but all I've found were shims for stem clamp area of handlebars, and nothing for grip area so far.

Does a thing like this exist at all? Can I somehow easily attach those bar ends anyway?

From the look of it, I don't think a shim like this could exist. That would be a very thin shim, with walls of 0.1 mm. Don't think it will be able to hold the pressure.

Can there be some durable tape may be, which I could apply to handlebar to increase it's diameter? I've thought about regular duct tape, but not sure it won't tear up under such pressure and torque.

How about some 0.004" shim stock? Most hardware stores have a K&S Metals display which should have it. Or McMaster-Carr has all kinds of shim stock materials.

I think a soda can wall is about 0.1mm thick.

^^^^ yes, a pop can wall is about 0.1mm. I measured this when I needed to use a 26mm stem clamp with a 25.4mm bar. It worked, but it slipped a couple of times so I eventually replaced the stem with a 25.4mm version. The bar end shifters shouldn't have much force on them at all, at least very little compared with a stem clamp. A shim should work just fine.

The leverage on the clamping area is much more on the bar ends than the leverage on the handle bars trying to spin the bars in the stem. Buy the right bar ends.

You’re thinking about it wrong. The ”squishiness” of a material trapped between two flat surfaces isn’t influenced by thickness. A thin shim of an appropriate material - soda can, shim stock... - will do just fine. You’ll crimp the bar before the shim begins to flow. What could POSSIBLY be an issue is if you don’t clamp it hard enough to keep the part from rotating. Then you MIGHT be able to tear a thin shim.

That suggestion has an immensely higher probability of not working. Tape will flow, squirm and smear under far lower pressures than something like a soda can shim.
