“I don’t want to use this *f##k* bike! What the *f##k* is wrong this bike!” he said, furious at seeing his chance of a second consecutive stage win pass him by. Cavendish started the stage on a limited edition Specialized Venge outfitted with brand new SRAM HydroR hydraulic rim brakes and Zipp wheels.
The quote is from velonews........too early to tell but he was using proven frame and wheel technology.....but new brake technology.....any bets on what he doesn't like being told to use?????

If I'm wrong that's ok - bottom line is some sponsor is causing him as a "poster child" to ride some gear that he feels is a detriment.......
