i was one of the street testers for this wheelset, back in the late spring. i wrote a review, lost it somewhere, and never got around to posting it. here it is, abridged:

The wheels were packed well. No axles poking out of the box, nothing tangled, nothing that makes you say "eek, i think i'm going to damage it somehow by pulling it out of the box."

My first impression was that the Formula hubs were smoother than I remembered my own set being; the wheelbuild was excellent - true and evenly tensioned. I tossed on tubes and tires and pried my cog and lockring off of my everyday wheels to put on this set and I noticed a tiny tiny flaw. The threading of Formula hubs could be finished a little bit better - it just makes it a little grindy threading it on the first time. Of course, grease was used liberally; and just going over the threads with the cog (screwing and unscrewing a couple times) cleans them right up. Not a problem by any means.

I rode these wheels for over two weeks, probably putting about two hundred miles on them. I rode them over the worst streets you've never ridden on, railroad tracks, cobblestones. Every so often I'd go over and check the tension and trueness, and it never changed.

Of course, that's not particularly surprising. Two hundred miles underneath a 135lb kid isn't exactly torture on a wheelset, even over some terrible roads, curbs, and a small stairway or two. Any flaws that might be present wouldn't be manifested until much, much later.

So for better evidence I'd look to the other IRO wheel that I had ridden for over a year. Built by Velocity using an Aerohead, stayed true and tensioned after more than a year of use. And I'd look to Tony's own experience with the XL-240's, with him weighing more than I do, putting 2500 miles on them. They hold up. I trust his experience and I trust the wheelbuilding of Velocity.
