Changing Handlebars?

I have riser bars right now I want to get some straight bars.
How do I know what width or bar clamp diameter of the handlebars to buy? I don't know my current width or bar clamp diameter.

Take the bars off and measure the diameter of the bars with one of these:



There are cheap and you can find them at hardware stores.

Also, most bars have either 26.0mm or 31.8mm clamp diameters. This isn't true for all bars but it is something to keep in mind.

A lot of risers are 25.4mm as well.

If you are just trying to get your bars lower, another option is to move your spacers around so the stem is lower, that way the grip area of the bars is at the same height.

Even if the bars won't fit your stem, you could always buy shims to fit your bars.

My is 24.5mm...wtf
All the handlebars I've looked at are 25.4...

I didn't measure it myself but the store I bought it from says its 24.5. Is there a chance that it's actually 25.4? Or no?

Yes. It is not at all unlikely.

Sometimes it is marked on the bar or stem.

Some older BMX bars are 22.2mm too.
I like finding rare or older bars that I like to use.
All the bars I have are different diameters, I have a bunch of stems & a few shims to make it easier to change up bars.

I agree, they need to make handle bars more "User Friendly".
A few shops I've been in say they "new" 31.8mm is the way to go...

It's not really so difficult, there are really only three standards; 25.4, 26 and 31.8

The 31.8's are huge and easy to tell from the other two, and the other two are so similar as to be a soda can shim away from one another. Unless you go really vintage and find a Cinelli stem, I think they are standardized pretty well.

Thanks, the store told me mine was 24.5 but im betting it's 25.4 because that's standard and it even says 25.4 on the stem.

But how do I change the handlebars? And how do I put the brakes from the first bar to the new one?

Time moves on, now 1.25" (31.8mm) oversize is the 'new standard'..

MTB bars use a different Tube diameter for their controls to fit on
than Road bike bars , 7/8" vs 15/16" [metric equivalent]
