i am not finding any of the info on my searches...someone with experience please answer a few questions. i weigh about 135 pounds. type of riding? nothing in particular, just whatever. it won't be anything too abusive i know that much.

questions:

1) in general, is a 36h rim adequate?

2) do people use butted spokes on 20" wheels? or did i notice that straight 14g was the best set-up?

3) do people use Al nipples? or is this no no? i would probably be using brass anyhow, just curious

1. If you're only 135lbs, you have no business whatsoever on 48h wheels.
2. Butted spokes cost about twice as much, but they are both lighter AND build a stronger wheel. See Bontrager's triangle: light, strong, affordable. Pick any two.
3. I wouldn't run aluminum nipples, the weight savings are minimal and the decrease in longevity isn't worth it, especially on a BMX wheel that'll see plenty of abuse.

Snazzy, want to do a write up in wheels for the new sticky?

i was looking for one!! i am paronoid to ask any fundamental questions here for fear of attack. i know how to use the search, but it doesn't recognize numbers or this would have been an easy find. i know it's probably been discussed many times. however, i have not been here many times.

i am familiar with MTB stuff, so are BMX wheels using more or less the same butted diameters/gauges?

Yep. Just shorter.

I heard that a 48H wheel with double butted spokes is only like 30% stronger than a 36H wheel with straight 14G spokes. So I don't know about them double butted spokes...

30% stronger with a small weight penalty. What's the downside?

Like for like a 48 is 33% stronger than a 36, and appx 2oz heavier.
I've not had experience with DB spokes on a 20", mainly because DT don't/didn't do them, but I'm not sure the arguments for their use apply to BMX, as our wheels have much more lateral force applied to them.
Even if you're not big, 48's are worthwhile purely from a maintenance point of view, IMO.

DT Swiss does not produce short butted spokes?? :(

they're my company of choice

They sure do! DT Competition 2.0/1.8mm DB spokes are available through QBP in 180 and 183-197 in odd number increments, and basically everyone orders from Q so you should have no trouble special ordering them.

Keep in mind that extra spokes and nipples are rotating weight, not fixed. Small differences matter. And if you're not destroying 36s (and I'm not at 165lbs) then why bother with a wheel that's 33% stronger than strong enough? If you *are*, then by all means run 48s.
