Hello all, going to buy two slightly used Cannondales next week for my wife and me... guy is selling it for a reasonable price. We're just going to use it for on road biking nothing fancy. Anybody got tips on purchasing? what are the weak points to look at? Also I need a carrier on my car, there's too many for example: http://www.hitchanything.com/2-Bike-Hitch-Rack/ ... need advise on that also, will it be best to pay a bit more or are the cheaper ones as good as? What is a common brand for these? I want one that is easy and quick loading and unloading... Thanks everybody!
