Hi!
Have you looked at any other bikes? The Ruby is absolutely fantastic...but don't limit yourself. There are lots of carbon fiber bikes out there...they're all going to fit differently and vary in price. I got a Trek 5000 this spring for less than $2K and love it. I think the components are comparable to the Ruby's.
You have LOTS of options! Don't focus in too early. I wasn't terribly interested in Treks when I started shopping and wound up with a bike that fits like a glove and rides like a dream!
Just my two cents. HAVE FUN!
