My initial impression of these wheels, before I owned them, was that they were flimsy. PVB had a set that he thrashed during a cross season and then on the road. Obviously with a wattage cottage like Pierre, who is known to destroy parts, the wheels gave up under the abuse (PVB later stated that he was happy with the wheels and admitted that they held up well under after he dogged them).
The front wheel went out of true early on. I trued it once and it has remained true ever since. I attribute this to normal settling of a machine built wheel and don't hold it against the wheelset.
While this is not serious either, its just irritating. I would just peel the stickers off, but that would create work for me and I'd rather just leave them.
