Chromoplastic Longboard Fenders offer the best protection available in a very lightweight fender. The Longboard offers extended full-fender coverage ensuring that your ride is free of puddle mishaps and water spray. The SKS Chromoplastic material is made using SKS Germany's sandwich technology, where strips of aluminum are embedded into plastic pieces. This results in a rigid, lightweight, corrosion resistant fender that can withstand all the elements you'll find on your route. The fenders also feature a secu-clip safety tab that breaks away if a stick or other debris becomes caught between your wheel and fender. Bolt on fenders take time and mechanical experience to install. Please take caution when ordering a bolt
