I have a 6 mile ride to work, which is mostly local highway.
I am considering purchasing a Cannondale Synapse 4 Sport Road Bike for my commute. I don't mind wearing a backpack for anything I need to carry (which is not usually much).
Do you think this bike is a good choice, or should I look at something else? I expect to pay $400-$700 for it, used with 400 miles.
