I spent 4 hours test riding bikes yesterday. I started looking at the aluminum/carbon frames and gradually moved on to the full carbon bikes. I bought a Trek Pilot 5.0 which is full carbon, Ultegra/105 drivetrain, cane creek brakes and bontrager race wheels. I really can tell the difference between a $1500 bike and a $2000 bike so I knew I had to get out of there before I decided to try a $2500 bike! I love this bike.
