And there is the point isn't it? In what other form of transportation do we think less of our body than our machine? All materials have advantages, even Bamboo, if you are into being green. ( Was really lusting after a Calfee about two yeas ago) But there is a reason for the N+1 rule. A different bike for different reasons. And there is a reason we don't often agree on frame material, Saddles, wheels or tires. Because we all have different needs. We as cyclists are in the minority. Recreation Cyclists may be the majority of that minority. Touring Cyclists are a minority in that minority. Vintage cyclists are in the minority of that minority. But they all have an opinion and needs that may or may not be met buy someone else's favorite material. But it seems as if the frame material of choice also corresponds to the number of riders in each group. The people in the minority simply tend to be more vocal about their needs.
