Carbon or Alu for Wife?

[purdyd]

I agree that components are also important.

The $2000 Trek Madone I mentioned earlier comes with Shimano 105, I think, which would be my minimum for Shimano. As it turns out, the bike I bought has SRAM Rival, which I'm quite happy with.

thanks everyone for all the great input

is there a preference for SRAM brifters for ladies over Shimano?
