The Rixen & Kaul Unidisc Chainguard is the first universal chainset disc, designed with break-resistant material and a modern aesthetic. Its innovative mounting system features a fiberglass-reinforced adapter socket that screws into the crank center, making it compatible with all cranks that have an inner thread. The disc is engineered to avoid contact with the chainring and offers fast, easy mounting with a single central screw. This chainguard is suitable for chainsets up to 48T.
