The original fat bike fenders! The Daves Mud Shovels are designed specifically for fat bikes - theyre extra long and wide to block the snow, water, or sand youll ride through on your next fat bike adventure. Made of heavy-duty polymer, the Daves 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, Venom, Megatron, and Prowler. NOT compatible with new 2.0 bike models
