Racks are pretty standard if you don't get one with special features. For example, I happen to have heavy duty Blackburn EX-1 racks on most every bike because they come with and fit the kid seats we own. Other than being bigger tubing, they're about the same as all the others.
Your road bike might matter, if it's one that doesn't have rack bosses.
