Thatīs a good looking bike. I had problems with fitting a rear rack with panniers as my feet kept hitting the heel into the panniers, due to the small rear triangle on my Cannondale M600 (1994). Couldenīt move the panniers long enough back without them get caught in the wheel in sharp turns. I had to make a modification to my rack. Have you experienced the same problem with your Cannondale?
