While perusing bikeradar.com's coverage of the Dauphiné, I noticed the coverage of the rider's lightened bikes for the climbing stages. There are a lot of methods the teams employee to lighten a rider's bike. Race leader, Bradley Wiggins, employed a couple of bikes with custom built light wheels. One element that was not employed to drop the weight on the bikes was the use of stupid light, non-functional quick releases. Instead, each wheelset used Dura Ace quick releases to secure the wheels to the bike. Lesson to be learned there. A solid wheel to frame/fork connection is vital to a secure feeling bike (and maybe pleasing the sponsors), but I prefer to go with their use as being the only acceptable QR to mechanic and rider and I'm sticking with it.
And yes, it is possible that the Dura Ace quick releases were one tool used to keep the weight above the minimum limit, but, somehow, I don't think so. Those quick releases look well used too.
