Having bought an aluminium road bike, and been very happy with it, it has constantly occurred to me that the only reason that Alu frames have a stigma is because aluminium is a relatively cheap material to produce bike frames from. If alu suddenly flew up in price, it would suddenly become a premium material. Do you agree?
I would go so far as to say that I prefer it from carbon fibre. My bike will withstand a real knock in a crash that a carbon fibre frame might get written off in.
