I used Ebay to make the base model bike a lot lighter than the 19.1 lbs listed. I replaced the wheels, tires, handlebar and stem, seat and post, brakes, and cassette for about $900 with majority of the parts being carbon fiber. Some parts were used some new and some free.
The wheels list for $1300 but paid $490 with free shipping and the 3TTT Ergosum LTD Carbon handlebars list for $400 paid $70 with $10 shipping. I just waiting to find a Sram Red group new for under $900. Also some parts came from my LBS my next project is to buy a Specialized Venge Pro Force and get it around 14lbs to use as my time trial and duathlon racer.
