Will a 24 spoke DT Swiss Powertap go out of true too easy?

Ariel

I am thinking of getting a wireless Powertap on a DT Swiss RR1.2 rim. I was looking for a 28 spoke wheel but I've only seen a 32 and a 24 spoke option. 32 spokes seems like over kill. But my old coach told me not to get a 24 spoke powertap because he said it would always go out of true. Anyone have any experience with the 24 spoke version going out of true? I'm 115lbs and I am hoping to use this wheel to train and race on.

Thanks,
Ariel

Depends how good your wheelbuilder is. At 115 lbs, you are not likely to be putting big stresses on a wheel, 24 spokes should be plenty. And if it does eventually go out of true, well get it trued! I'm pretty sure you can get 28 spoked hub though.

Well...24 DT competitions spokes, PowerTap SL 2.4 and American Classic 420 is strong enough for a 175lbs rider so stronger rim under your feathery 115lbs will work just fine. Just make sure to use good wheelbuilder.

I was thinking of ordering the wheel online. Perhaps that's a bad idea?
So how do you know if someone is a good wheel builder? Are there questions I should ask that would give me an idea if someone was a good wheel builder?

Thanks,
Ariel

I'd ask Rich what he recommends re: spoke count.

I just had my rear DT wheel completely rebuilt by www.excelsports.com and they did a great job through out the process. They also build using the PT hub. You can use their wheel builder page to go through and build using a variety of rims and spokes including DT products. They were also good with customer service and returned my phone calls to expedite the order so I am sure you can contact them for any questions. They also have a live web question service as well.

At 68 - 70 kg (~150 lb) i used to ride my CXP14 wheel daily on some cr@p roads. This was a 24 hole, 30-mm rim on a PT Pro hub. Never went out of true. Used it for training and racing and wasn't careful about avoiding pot holes etc.

Also I notice that you are specifying the DT 1.2 while the DT 1.1 is lighter by 168 grams. I am ~164 and have had no problems with the wheel set (until a bad crash ).

At 115lbs you could probably (easily) use the DT 1.1 with Revolution spokes on a 24h PT hub.

Edit: I just noticed on the Excelsports wheelbuilder that it doesn't have a 24 hole DT 1.1 rim. Starts with a 28 hole, but it is still light.

Thanks everyone for your input. I think I'll be happier with the 24 spoke count.

Cheers,

DT Swiss has for 2008 a new model, with a reduction in weight, 50-60 gram compared ro RR1.2, the model is R520. But still is the height and semi areo design almost the same asfor RR1.2. I do not know what it will cost. Holeconfig is 20,24,28 or 32.

Or you can get a Niobium 30mm rim, which weights 460g. Cheap, too.

THat's what I'm having built. Nobidium rim (from BeyondFab) 2x sapim bladed spokes. I'll let you know what the wheel weighs when I get it back.

From a price/performance view the Nobidium rim blew everything else away even allowing for getting it imported form the states.

i can also vote for Rich at wheelbuilder.com. He knows his stuff and my experience has been great - top customer service as well. Bought 2 sets of wheels through him

FYI - 70kg (154lbs), DT Swiss RR1.2 [edit was RR1.1], 28 spokes PT SL 2.4, Sapim cx-ray spokes. This is my training wheel (& some races). Only issues (minor) i've had have been hub related.

Also bought a set of Zipp 404's w/ PT SL 2.4 from wheelbuilder - again, no issues

I cannot recommend the DT swiss 1.1 rims, mine required way more care than should be needed for a rim of that style and despite a lot of care the rim eventually failed.

If you purchase a preassembled powertap I would take it to a wheelbuilder and have them tension balance it and true the wheel. Mine wasn't even close out of the box and some of the spokes had almost no tension on them at all.

My powertap has been rebuilt with an Open Pro rim and after seeing the problems that the DT Swiss 1.1 had (around the eyelets especially) I cannot see me ever getting another. It made it about 3000 miles which is horrible considering I have Open Pro wheels that I have been riding for several years without any real maintenance at all.
