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

I know I posted this myself some time ago. However I'm planning to order a PT SL 2.4 hub for myself and was thinking that would it still be better to get 28h hub since I weight porky 78-79kg/~175lbs at the moment. I'll get that down to 73-75kg/160-165lbs before the spring comes though. I'm going to build it to Kinlin XR-300/Niobium 30/Cadence Aero rim so I think 24h should be strong enough for me, but would four more spokes make it conciderably stronger without trading in too much aero benefits? Not that this is super aero wheel to begin with.

Roads here are pretty bad or sometimes very bad. 24h hub, two cross DT Competitions, 30mm rim or 28h hub two cross DT comps or Revos, 30mm rim???

I apologize for not checking back in a bit but regarding the spoke tension, yes I feel like it was pretty obvious. Each of the spokes that are on the same side of the hub should to a certain extent be under the same amount of tension. Mine out of the box had spokes that looked like they had been laced but never adjusted, it was round but there is a little more too it than that.

That's why I suggest taking those prebuilt wheels to a shop, I would think any shop that builds wheels would be able to check the tension of the spokes and if its not in the powertap manual then they will be able to look up the right tension for that particular hub and the way that it is built up. A quick check at home is too pluck each of the spokes they should have kind of a musical note to them, if one is too loose to pluck or sounds a lot different than the rest you might have problems.

Tension is actually specified by the rim manufacturer. Most popular rims (Mavic OP&CXP, Velocity, DT, etc) recommend 110-120kgf for the rear. If you send the Mfg a quick email, they'll probably tell you what they recommend.

Your right its not in the Powertap manual, at least not mine, there is some pretty specific information in there as far as how they think it should best be built up but not the tension. DT Swiss has a chart for all of their rims on their website, though it is in Newtons.

One thing I noted when I was looking at that chart on their site is that all of those DT rims have a weight limit placed on them, its not that low but I am little suspicious of an aluminum box section rim that has a weight limit similar to what you see for most extremely lightweight rims.

Here is a question for one of you: DT always known for their spokes made hubs for awhile under the Hugi name (and I like my DT hubs) but how long have they been making rims under their name or another?
