I have a pair of Planet Bike ATB Freddy Fenders I want to mount to my mountain bike. It has 26" wheels. I unfortunately don't have the instructions, but I do have nuts, bolts, cable ties, and a screwdriver set. My LBS says the fenders are meant for 700c wheels, but that doesn't make sense to me; most ATB's >are< 26". I'm fairly sure they'll fit.
