I'm using my bike more and more for running errands and shopping so I am looking to add a rack to my bike so I don't have to shlepp everything in a back pack! I saw the Topeak rack over on the REI site and really liked the idea of the quicktrack mounting system. Anyone on here have this type of rack? How do you like it? I have a Giant FCR, would this rack fit ok? Any input would be great!
