TC Bros Raw Steel Flat Bobber / Chopper Fender TC Bros flat profile fenders are specifically designed for the unique needs of motorcycles, distancing themselves from generic trailer fenders that fail to properly match the contour of motorcycle tires. Suited for both 16 and 18 rear wheels, these fenders have a 27 diameter to ensure a perfect fit. Crafted in the USA from durable 14 gauge steel, they are built to withstand the rigors associated with hardtail rigid frame choppers and bobbers. For a custom application, they come un-drilled, giving you the flexibility to cut and drill as needed. Features: Raw steel, un-drilled for custom applications Heavy duty 14 gauge 27 diameter (13 1/2 radius) Made in the USA
