All anecdotal evidence I'm afraid from a friend of a friend's best mate's uncle's dog. I definitely recall a race team who had Cero wheels and who had major problems with them, but that was quite a while ago. I'm a total Light Bicycle fanboi though, so treat anything I say about other Crabon Fibber wheels with caution.
Good wheels? Looking at a set of 38mm rim brakes from them (novatec hubs I guess) and despite having had Chinese frames before am more concerned about exploding wheels than a disintegrating fork (no idea why).
