I saw a picture of that bike on Cannondale's web site, and I could not determine whether rack threaded eyelets were available on the fork and dropout. If they are present, then it will be easy to attach regular racks to that bike. If eyelets are not present, then your best option is to use racks that don't require eyelets -- Old Man Mountain has such racks:

However, given this picture of an F500, I think regular racks are possible (this bike seems to be loaded for serious touring):
