who to convert rim width from metric to imperial

(1/3) > >>

kalex:
i'm after a 26 x 2.125 rim but the wheels i fancy are only in metric

so how would 2.125" read in metric conversion as i'm sure it's not as simple as 1" = 25.4mm

i've been on sheldonbrown and i'm more fooked than before i looked on there

MartyC:
What sizes are they in metric?

If they are listed as 700c then dividing the 700 by 25.4 will give you them it in inches = 27.55

It's the rim width I'm after

there 26" rims and I Want as close to 26 x 2.125 as possible but they just say 599/21, which is 26 x ? I presume 21mm but what is 2.125" in rim width as I'm dame sure it's not 2.125" x 25.4 = 54mm wide.

There must be a way to calculate it or a conversion table

Tel-boy75:
I thought they were two different sizes all together. So a 20 x 1 3/8 rim is actually taller than a 20 x 1.5. Something to do with the measuring techniques, so although they are listed as 20s they are actually different heights.

Dark Diggler:
26 x 2.125 is a tyre size, not a rim size.
You can run that tyre size on any 26" rim pretty much

As a guide to rim width

21mm rim-cross country, typically 1.75-2.125 tyre
33mm rim-freeride, all mountain, typically 2.125-2.5 tyre
33mm+ rim is downhill and typically 2.5 + tyre.
