It's not the rear wheels that are the problem, it's the front wheels. i'm short and sit close to the front wheels. Rear wheel spray doesn't hit me because I barely am taller than the seat back, lol, and I have a backpack hanging down the seat back. no rack- i took it off. i use my burley travoy instead.
