DH is pushing hard for me to buy a bike for Christmas (before you think I'm very lucky (I am) know that it gets him out of the mall for Christmas ).

Titanium is nice but I don't want to wait for a custom bike - plus if it doesn't fit it's a 50/50 deal - I own both halves. So, I'm looking at carbon fiber.

It seems like there are various ways that carbon fiber is made. For example, on the Trek website, they say that the Madone 6.0 series has their high end carbon fiber frame. But, what does that mean? How is it made? Am I over-thinking this?
