I recently bought a pair of SKS P45 fenders for my Trek 7.3 FX from AEBike.com but they didn't come with mudflaps. Lots of threads around here recommended mudflaps and many suggested making your own but I didn't want go the Fred(hope I'm using that right) route. Wallbike carries SKS mudflaps but they seemed a little short to be very effective so I kept searching. I knew Planet Bike carried small parts for their fenders so I decided to take a chance on a pair of Cascadia Hybrid flaps. They fit the SKS fenders perfectly, look stock, and provide great coverage. Now I'm ready for any slop the street throws at me. Well almost any.
