Looks pretty nice. Installation was fairly simple--as long as you remember to serially tighten all the screws as you go, the cover centers itself pretty nicely on the wheel.
Wheelbuilder.com did a nice job pre-cutting for this wheel--a Reynolds Solitude.
It's a little involved because you have to remove the cassette, etc to install, but that's no big deal with the right tools. I'll be using it at a tri next weekend... It'll do while I save up for my Zipp disc.
