Carbon Rims?

OK, I admit ignorance on this (a dangerous thing to do on RBR...).

VeloNews live Vuelta coverage says, Stage 9: "4:35 p.m. Up front, the lead
group has dropped Cardenas on the descent ... he is being extra cautious on
the wet road, apparently reasoning that you can't win if you finish in the
ambulance. Our man on the scene, Charles Pelkey, notes that he's using
carbon rims, which may be a factor."

Why would carbon handle less well in the wet than metal rims?

Slippery rims that brake pads don't grip as well.

Al

Less braking on them when wet.

Thank you. Wow, I didn't know carbon had that problem.

Yowch! Thanks for the graphic demonstration of carbon rim's braking
problem...

Surprised mfr's don't have a fix for this. You'd think bonding a metal race
would be doable.

It's not the rims handle differently. It has to do with the braking of wet
carbon.

I have no experience with carbon rims other than following and
watching the "grabbiness" of braking of riders in front of me with
carbon rims but in carbon rims' defense it appears that Bill says in
that thread he was not using the correct pads. Zipp and Hed make
structural carbon wheels with AL rims but Zipp insists on users buying
the Zipp pads still.
