So I wanted a fender that only mounted on one side of the fork. The original design I came up with seemed good enough, after all there’s not much of a fender. While off loading the bike one day I heard the fender make a “tin can” sound. Needless to say that drove me nuts. So back to the drawing board I went. I made the front of the mount more robust. I knew I also needed to stabilize the rear of the fender. I made a detachable strut that wraps around the fork and mounts to the rear of the fender. I decided to wrap the strut in fiber glass to save weight. The fender now has the rigidity it needs to keep things quiet.
