Portland Design Works Dave's Mud Shovel REAR Fat Bike Fender;

The original fat bike fenders! The Dave’s Mud Shovels are designed specifically for fat bikes. They are extra-long and wide to block the snow, water or sand you’ll ride through on your next fat bike adventure. Made of heavy-duty polymer, the Dave’s Mud Shovels are super lightweight but sturdy enough to take years of harsh weather abuse. The rear fender mounts in seconds to your seat post for easy on/off depending on riding and weather conditions.
