Can I lace a 24h to a 32h hub?

Can I lace a 24h to a 32h hub? I'm trying to convert my single speed to fixed.

Thanks

It gets very complex. You will end up with multiple spoke lengths. Better to get matching parts. This question is much better asked in the mechanics forum.

Specialty racing time trials? forces in stopping a fixed gear bike are high on the street,
sudden stops to not be killed in a collision, a prime example
I'd get a common 32 hole rim for the rear,

sell that rim to the next guy who will be asking will A fit B soon.

maybe that's where this rim came from .. someone else asked a similar question a day or 2 ago.

you can lace it if it the hub has uneven dishing, but if you want to lace it to a hub with even dishing on each side, then lace it up to a 36h.

you use 2.19x, or roughly a 2 cross length with +2mm when lacing a 24h rim to a 36h hub. The spokes go in pairs with one hole skipped between pairs.

Maybe as a front, not a rear , a front you can use a radial lacing skip 4 holes in the hub on each side .

Could you explain the reasoning there?

for a rear wheel, if the rim doesn't have a lot of difference between left and right spoke holes, you could try triplet lacing, 16 spokes on right side and 8 on left. In theory you end up with more even spoke tension but less lateral stiffness.

if there's a lot of dishing on one side, then the spoke tension will be low on the opposite side, so you can take out half the spokes, 32h/2/2= 8 to bring up the non drive side to adequate tension.

When done with a road hub, it's about 100% drive side, 85% NDS spoke tension.

It is, but you'll need to lace it radially or use a few different lengths.

360/(48/2) = 15. So the spoke holes on a 48h hub will be 15deg apart on each side with a 7.5deg offset between the two sides.
360/(24/2) = 30. So the spoke holes on a 24h hub will be 30deg apart on each side with a 15deg offset between the two sides.

What will happen is that ONE side of a 48h hub will match up perfectly, BUT the opposite side will be be off by 7.5deg and give you all sorts of headaches.
