I think that using carbon fiber for any use that involves frictional contact is a big mistake. Carbon fiber resin simply is not strong and cannot withstand this type of use. I wouldn't be surprised if Campy changes the Record cage material back to aluminum or titanium in 2009.

When will the carbon fiber-can-do-no-wrong madness end? (I know alot of bikers who are going back to aluminum wheels after having failures with their carbon fiber wheelsets.)
