These wheels tick all the boxes in terms of low weight, good aero, good braking and relatively reasonable cost. I've used them in several crits plus a few longer events. Braking is very good, maybe on a par with alu, but hard to say. On a long ride I descended one of the more challenging hills in Malibu (Deer Creek) and I had no problems with overheating or loss of modulation. I'm very happy with these wheels. Maybe the high-end Zipps or Enve's are better, but I'd be surprised if the difference would even be noticeable for most of us amateur riders.
