I second what troysmith80 stated, everything you need to install the free radical to your bike comes with the kit. Now the tricky part is deciding on the accessories. I went with the HD racks just because I had intentions of using my Ortlieb panniers, but never did as I ended up buying the freeloaders. The Freeloaders exceeded my expectations in just about every way. I didn't want to get them as I thought they were too expensive, but they are so functional. I also have the whatchamacollars on all 4 ends of the racks and top it all of with the Flightdeck. Are you planning on transporting adults or children? I transport my two boys so I installed homemade stoker bars and have a Peapod coming in the mail for my almost 2 y.o. The Kickback is handy too, though I'd say try the kickstand that comes with the free radical to see if you need to upgrade. The last thing I'd say is make sure your wheels are up to the task for the loads you plan to haul. I've been using wheels I had from old mountain bikes and the first rear wheel popped a spoke and the current one I'm afraid is too lightly built. I just got a heavier duty rear wheel that I will swap out. Your front wheel is not as important as long as it is decent and not worn out.
