I...We are on our second Cannondale, the first was I believe a '99 base model RT1000, with lowerend components. We had it and enjoyed it for several thousand miles replacing drivetrain parts as needed. We later sold the frame to an avid tandem racing couple who wanted the frame due to it's legendary stiffness. We now own the higher end (discs and upgraded drive train) 2007 Cannondale Tandem. Althought the geometry has changed, (compact design with lower top tubes), it's still a great value for the money compared to other more expensive tandems. We did test ride a Trek but found it to have a flex feel--just our opinion. Congrats on your purchase...get out there and ride, and learn to how to work on it, something I've also grown to enjoy.
