Sapim CXray spokes

I have noticed on some of these higher end wheels, such as Zipp, they use Sapim CXray spokes. Well I did a google and there really isnt much information on them! I went to the Sapim website and they had information but really not a huge deal. Has anybody used these things? It appears that even though they are aero spokes, they still fit in the spoke hole so you don't. have to slot your hubs (and voiding the warranty of the hub). And do you need to use special nipples? Just curious

I rebuilt a set of American Classic hubs with Zipp 404 rims with them. They're supposed to be super strong, and from just handling them while building my wheels, I can say that they're very springy as opposed to normal spokes which are more malliable, and they seem to be able to take an huge amount of tension. You don't have to use special nipples, but the Polyax nipples are great because you don't need spoke prep, and they have a plastic thread locking material which lubes the threads and prevents loosening. My wheels built up nicely and haven't gone out of true after about 1000 miles. They are expensive, but I'm happy with them. I won't use anything else now. I bought them over the net from a place called Thorusa.com. I couldn't find much else about them either, but lots of high end wheels use them.

About Sapim -

The CX-Ray would be their high-end spoke, it is bladed, but only 2.0mm long, so it will fit standard hubs, and standard rims. They are one of the greatest strength to weight ratios of any spoke. Even Lance Armstrong and US Postal rides them when they are not being paid to ride Bontragers or Ksyriums. Also, many DHers are known to ride with them. How many products can you say are used by both Lance and Dhers?

I use the lesser expensive Sapims myself, the Leaders and the Races. They are all made from that "springy" steel, they do tend to lace up much better. I am a big guy, so I usually build wheels with very high tension and sometimes a 360degree twist at the cross, depending on application. I have NEVER broken a Sapim spoke, and I have made some road wheels that were just absolutely CRANKED to max tension.

Some decent info on them is available at www.thorusa.com, and he also sells them.

The only downside I know of is that they are MFing expensive. Something like $2.50 PER spoke.

A friend of mine has the Twist model built on a set of mountain wheels. They are CX-Rays twisted, so the built wheel looks bling-bling kinda lowrider style.
