I ride a 1997 Trek 5000. One of the original all carbon fiber frames. Unfortunately it's pretty old school compared to the Madone. I still love it and put well over 1,000 miles on it this year! My new horse will be a 2008 Cannondale Scalpel 4 I can't wait to get it and put it through it's paces!!! How about you, what do you ride?
