One problem to note with plastic fenders like SKS and Zefal - ones I bought were warped, which is totally annoying because they don't have enough attachment points to straighten them out. I had to zip-tie my rear fender to the rear rack to straighten it out so that it didn't rub the tire. The front looks totally funny because it isn't in line with the tire. Buy them in a store so you can make sure they're straight or at least return them.
