TC Bros flat profile fenders are among the highest quality you will find. Unlike others on the market, these fenders are actually designed for motorcycle use. This is not another re-labeled trailer fender that doesn't fit the profile of a motorcycle tire properly. These fenders feature a 27" diameter (13.5" radius) that follows motorcycle tires made for both 16" and 18" rear wheels. They are proudly made in the USA from heavy duty 14 gauge steel to survive the abuse that hardtail rigid frame choppers and bobbers can provide. They are un-drilled for a universal fit, allowing you to cut/drill to your custom application.
