Thanks Doug.
The Packer Plus is too large and heavy. 20 ounces heavier than the Roller Classic. Thanks so much for the information. Its just what I wanted to hear - a user of the Volpe with the Roller Classic rear panniers and no heel touch.
I am getting the Tubus Cargo rack from Wayne.
Nice bike - what is the front rack and which fenders are you using? What tyre?
Sorry for so many questions but I have never toured before and am pretty new to cycling itself.
