Just a note on that cyclingnew.com article quoted by Double-avodados. His quote about durability really confuses what we were discussing with him, that since CSC is the only team where every rider gets full carbon wheels for every racing day of the year, they will break more carbon wheels than other teams, where the domestiques get heavy beater wheels and the whole team gets special Classics only wheels. Having said that, the team consistently tells us that they break fewer wheels overall than other teams, but far more carbon wheels as everybody else uses their carbon wheels so sparingly...
Breakages come generally from crashing and from the guys running to and from the team cars when they are completely unsighted by the cars and other riders, run off of the road, crashed, and generally otherwise abused. Remember, these guys are racing at 50+ kph for 200+ km at a time on roads that we would generalyl consider to be nearly unridable. Also we discussed, but they failed to mention that the breakages are not simply broken and unridable wheels, but simply cracks in the rims. Of the 8 rims broken at Flanders, 4 of them were broken in crashes and 6 of the wheels were finished on an only discovered to be broken afterwards as the failures were simply cracks in the perimeter of the rim. Believe it or not the team was quite thrilled as most teams use their aluminum wheels for the one event and discard them aftarwards as they are generally bent, hopelessly out of true, stress-fractured and everything else you can imagine.
The mis-statement here is that the wheels will NOT eventually break until you hit something, crash them, or whatever. There is no fatigue type issues here with the wheels, so they only break when impacted or cracked due to some extreme stress. If you are just riding them and training on them and never crash or impact them sufficiently to break them, then they will not break due to fatigue.
