Race wheels - Hed or Zipp or other? - Page 2

That's right about spokes going slack, but the tension needs to be high enough. The biggest problem with pre-built wheels is uneven tensions and tensions that are too low.

Neuvation are doing carbon clinchers in a few different sizes. They mostly use American made rims too (reynolds??)

If cost is an issue find out what sort of deal you can get from them.

According to the Neuvation web site, the C50 CF rims are made in China.....dunno by who. The other CF rims are US made, but the rim dimensions don't match Reynolds stuff. I'd guess that the rims are non-dimpled Zipps.

Reynolds, unlike Zipp, doesn't generally sell their wheels to other manufacturers to be built into wheelsets under another name. The do sell one or two types of rims to Tune, in Germany. Reynolds likes to have tight control of what happens with their rims. In fact, up until at least last month, there was only one custom wheelbuilder allowed to buy rims directly from Reynolds (The Wheelbuilder, I think he's called.).

I reserve the right to be wrong about who's providing said rims for Neuvation.
