The YBN MK747SL is a high-performance single-speed chain designed for track, BMX, and fixed-gear bicycles. Engineered for strength and reliability, it features hollow pins and side plates to reduce weight without compromising durability. The chain is constructed from SCM steel, ensuring exceptional tensile strength of up to 1,300 kgf, making it ideal for the high loads encountered in single-speed cycling. With a standard 1/2" x 1/8" dimension and 112 links, it is compatible with most single-speed setups. The silver finish not only enhances aesthetics but also provides corrosion resistance for extended longevity. Additionally, the chain includes a reusable quick link for easy installation and maintenance.
