I'm trying to build up a wheel with a rear 28 hole dura ace hub and a 24 hole zipp rim. Am I wasting my time? Anyone been there?

That doesn't seem like a good idea. I think it might be worth it to spring for a cheapish 24 hole hub.

ha, ha, ha.. I know but that would be too easy. BTW, anyone have a 24 hole rear hub they want to sell? OR does anyone want to buy a zipp 400 24 spoke on a 28 spoke hub... cheap! LOL.

Almost, but no.
For a 24 hole rim, you need a:
12 spoke hub
16 spoke hub
24 spoke hub
32 spoke hub
36 spoke hub
48 spoke hub
You should be able to find a suitable hub for whatever you can sell the 28 hole hub for.

THANK YOU SO MUCH SUPERDAVE!

Ok now that I am using a 32 hole hub, can anyone (SuperDave) explain the lacing pattern?
Re: Can you build a wheel with a 28 hole hub and a 24 hole rim? [NYSLIM]
[ In reply to ]
Can't explain it, but pretty sure you'll have 8 holes on your hub without a spoke. No need to thank me for this....

I had a 32 hole Campagnolo Athena Hub laced to a 24 hole Mavic CXP 14 rim that I rode for 21,088 miles without ever truing the wheel or servicing the hub. Here is how I laced it:
The drive side used ALL of the spoke holes. The 16 holes were laced with DT Revolution 14/17 guage double butted spokes and extra long brass nipples. The parallel spokes were laced to two consecutive spoke holes in the rim, without skipping a hole. The spokes on the drive side that skipped a hole were the ones that crossed. Be sure to place the valve stem hole between the two parallel spoke so it is easier to use a pump. The non-drive side is laced radially with the spoke heads showing on the outside with only HALF the spoke holes being used. The holes in the rim left unfilled will line up with a spoke hole in the hub and that is the hole that is used. The spoke should go between the two drive side spokes that cross. Use a thicker guage spoke on the non-drive side. I used Alpina Aero 14 "straight" guage spokes with extra long alloy nipples.
This lacing results in almost equal spoke tension left to right resulting in a strong wheel and durable spoke life. After building, truing, tensioning, stress relieving and retensioning, I ride the wheel for about 20 hours and locktite the nipples.
Two years after I rode this wheel, Campagnolo introduced G3 lacing in their aero wheels. Pairing two spokes on the drive side for every non-drive side spoke.
I was flattered.

Same as Super Dave. I built a cheap Sun rim on an American Classic hub. I don't remember the count anymore but I know they were different. I rode them for 4 or 5 years and sold them to a friend who weighed 220#. He rode them a couple of years and sold them to another friend and they are still going.

How about building a rear wheel with a 24 hole hub & a 36 hole rim? What kind of lacing pattern would you use?

drgracer,
Just curious. How do you plan on plugging the unused holes in the rim to keep the tube from pushing through, ballooning out and exploding? What do the "experienced" wheel builders do to manage this obstacle?

you'd need to be sure there was no angled spoke bed on the rim, then you could lace spokes into the hub and skip every third spoke hole a la Bontrager or Alex's paired spoke designs. You get two spokes close together, skip a hole, then two more spokes close together, skip a hole and another pair.
I've done wheels this way as well, but the wheel is not as strong as a regualr 24 wheel with an angled spoke bed. This pattern will work for front or rear wheels however.

I laced a 36 hole hub to a 32 hole rim. No problems. And it's a SS commuter wheel. I just skipped two holes on each side of the hub (180-degrees opposite on one side, clocked 90-degrees on teh other side).

SuperDave,
Duh.
Thanks for your reply.
But its not really so Duh when you consider that most spoke holes in a rim have a spoke nipple in them. Remove the nipple and the opening in the rim is considerably bigger. I didn't think a rim strip (even a Velux) would be sufficient to get the job done, especially over time.
Just evidence of my ignorance. Consider my posts with caution, I'm ignorant.

but the hole from the double wall rim isn't plugged and the nipple doesn't provide a pneumatic seal.

That is quite slick! Here's one more math problem for you--I have a 20 hole rear wheel (deep carbon variety) that I'm required to race due to sponsorship considerations, and I want to lace a PT hub into it.
Will a 24-28-32 work?? And which would work best?
Also, how the heck do you calculate spoke length?? (rim rods??)
Thanks.

Ah here is where those darn sponsors get in the way. I'd suggest you contact Ritchey, Rolf or Bontrager or whoever and see if they'll do a 24, 21, or 18 hole drilling on a blank rim.
Powertap might do custom drilling too, but a standard hub drilling won't work with 20 hole.

Funny you should ask. I just purchased a used 24 hole Bontrager rear hub off eBay, but the rim I hoped to use it on didn't come through. I got a notice this morning that the hub has been shipped, so I haven't seen it yet. I'd prefer to buy your rim, but am willing to sell the hub after it arrives. Contact me at steve@telecomreg.com if you want to transact business off line.
