Carbon road wheels?

I'm not claiming they are, having not ridden a pair I'm in no position to comment but guiding in the Pyrenees this year tells me that they're definitely not wheels that brake-happy freds should use...

Descending - braking in the mountains =

a) he was probably so off his tits on drugs he'd lost all sense of control
b) it was pissing down
c) the corner where he went over the edge creeps up on you and is far tighter than anything else on the descent
d) he wasn't actually using carbon rims, but aluminium ones
