The Surly Clown Shoe Rim is a wide, rugged rim built for fat bike applications where flotation and tire support are essential. At 100mm wide, it's designed to handle the biggest tires on the market, giving you increased traction and stability in deep snow, sand, or loose terrain. The dual row of spoke holes helps distribute stress more evenly, improving wheel strength. Made from 6061-T6 aluminum with a welded seam, it’s tough enough for extreme conditions yet still tubeless-compatible for modern setups.
