Since I had a hard time trying to figure out just how much coverage the Freddy clip-ons SpeedEZ have, here's how they fit my ride for those trying to make purchase decisions. Those are only 30 width cx tires, but the limiter is my frame clearances, not the fenders, which themselves are 45mm wide. They give you plenty of length on the rubber band fasteners--I just did two wraps of them to take up the slack. I could have trimmed them and kept the other halves as spares for later. My pop bottle "mudflap" is just ducktaped over the stock bs "mudflap" that comes on the fender, and is pretty much useless--but does give the fenders a more "finished" look.
