Is a 1mm stem shim remotely possible?

[mcmoonter]

My elderly aspiring touring friend bought some Brompton butterfly bars. They didn't match his stem diameter. He popped back to the shop to be told his stem diameter was 25mm and his bars 24mm.

Both are dimensions I've never heard either of before. He was told he'd need a 1mm shim.

Does such a thing exist or are the dimensions wrong?

The stem was similar to this. It was fitted to a Dawes Karakum, I'm not certain of the year model.

Coke can shim?
BTW both items sound none standard sizes to me

[Brucey]

the stem is probably 25.4mm. Some older Brompton handlebars were 24mm, but even they have realised that it is a daft size and now use 22.2mm ones.

I have machined shims to fit odd handlebars to odd stems before now. However I would take the view that the easiest path would be to buy new handlebars with a 25.4mm clamp size.

Cut some bits from a coke can you made need two to get to a mm.

1/2mm!

Try rolling a 1/2mm bit of steel sheet by hand around a 1" piece of tube!

You can buy handlebar shims.
