Anyway care to comment on their experience of such frames. I have been considering high quality alum. alloy ( Scandium ) framesets with both carbon seat + chainstays ( and forks ).
Ta for any comments.
 
I've got one of them (Guess SC1) exactly as you describe.

Er, it's a nice bike, very light and fast. The only drawback (and I've seen it said about other scandium framed bikes) is that the tubes are made from very, very thin metal. You can compress them with your fingers (DON'T TRY THIS AT HOME KIDS!). One prang and you've got a crushed coke can with wheels. Depending on how much you want to spend I'd be tempted to go for a titanium frame. You can always get bargain basement parts and gradually upgrade.
 
I've a Rocky Mountain Vertex Team Scandium (Easton Scandium main tubes) and love it. In terms of its strength and rigidity it has totally coped with anything I've been brave enough to throw it at. Although its lack of weight makes it a pleasure to ride one of the, surprisingly, really nice things about it is how easy it is to portage, lifting it over stuff never fails to put a smile on my face.

I think we have to assume that for any given discipline; XC, TT, DH, Track etc, it's highly unlikely that a frame made by competent manufacturer will fail under normal use. Scandium frames are no more likely to fail than any other material if the frame is well designed and built. But then, my mate's custom built Merlin developed a crack around the seat clamp. Which raised a few eyebrows I can tell you.

Under normal use yes, fair enough. But the incredible thinness of the tubing is such that even an everyday accident like say, dropping it against a bollard, could easily put an irredeemable dent in the tubes. That's the factor that will ultimately limit the lifespan of my SC1, rather than frame failure from regular use.
