The Dave’s Mud Shovels are designed specifically for fat bikes-they’re 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 bad weather abuse. The front fender mounts to the down-tube of your bike using adjustable rubber straps for a secure fit. For use with: All Rambo Bikes with the exception of the R350
