Keep your bike chainring clean and protect your clothes from grease with this simple plastic guard. It’s designed to fit Shimano cranksets like the M430, M590, and M390 (max 44 teeth) that have four screw holes. Made from tough, lightweight plastic, it’s wear-resistant and helps prevent scratches and dirt buildup on your crankset. Installation is straightforward – just use the provided screws and gaskets. Note: some cranksets might not have threaded holes, so you may need to tap them yourself. A handy, low-cost accessory for mountain bikes and road bikes to keep things tidier.
