How well does stem and bar size have to match?

Couldn't find a previous thread about this (possibly stupid) query; how well does the sizes between the stem clamp (quill, in this case) and the bars match? Would it, for example, work with a 26 mm bar in a 26,4 mm clamp?

26.0 bars with 26.4 stem is fine.

I would be very wary about bars smaller than the clamp. The clamp is that size for a reason.

Thanks! I guess I'll just have to find out and report back here.

One of those things I'd do myself, but never recommend to anyone else.

Sheldon is cool with 26-26.4? I wouldnt try any other combo without a shim shimmany tho.

Inverse shim can help, especially with mismatched bars.

Find out what exactly?

That things that are different sizes don't function as intended when combined?

Hurry back: a nation (of dentists) awaits...

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
