If your frame has mounts for a rack then you're good to go your rack will be part of the bike only. Looks like the one you linked will mount up just fine and is set back (so you don't kick your bags) which is nice. Really, the only reason to get a topeak rack is if you're going to use their accessories that mount with the track. I use the topeak setup to ride to work but I just have a trunk type bag for lunch most of the time. Don't think topeak makes bags that i'd say are big enough for a big grocery run.
