It may be be possible to join carbon to an alloy mounting but to be honest, it will be an expensive rarely seen and not much lighter than an alloy strut brace.

Nobby Unregistered N	Just for info: I found this on the web a while ago and its quite interesting, I'm sure the same could be applied to making a strut brace http://www.bmeres.com/carbonframe1.htm

alfisti Unregistered A	maybe something like bicycle seat post .. core is made from alloy and rest is made from carbon

THE_G Unregistered T	what would be the point of that ? its hardly going to save much weight or make it much stiffer better just using plain alloy
