This is no longer much of an issue according to the most recent VeloNews test. They cited their own carbon clincher failure from heat buildup during a test three years ago. Now they mention due to new resin technology and better design, that's no longer a problem. What's interesting is they mention the latest wheels are fine even for occasional off road dirt riding and are okay even in wet conditions.
