(Mr MC posting) CF cannondale vs mallett all very impressive. If you routinely crash your top tube into a mallet. Youre more likely to hit, ooh, lets say a sharp-edged rock which WILL put a scratch/gouge in it.
I would like to have seen him put a gouge in it and then beat the hell out of it.
As a former professional materials scientist, the one thing that puts me off CF frames (and drove me from buying an Ibis to a Nomad) is the "notch sensitivity", ie. how much weaker it gets after a notch or scratch. One of the few things I remember from my undergrad composites lectures (I specialised elsewhere) was the headline number "90%". Thats a lot of strength to lose in an otherwise innocuous trial-riding incident.
What I WOULD like to hear is what SC, Ibis etc have done in their manufacturering to circumvent this problem-multiple layers, different lay-ups etc, as I'm with WCA in that CF is ideal for full suspension- builds a really light and stiff structure joining the suspension components. SC are hyping the CF Blur to be tough and I am keen to be convinced with something other than marketing speil.
