These plates are designed to engage with the teeth of the bike's rear cog, which is fixed in place and does not rotate independently of the rear wheel. The chain is typically sized to fit the specific bike frame and gear ratio, with the correct number of links to ensure proper tension and smooth operation. Like other bike chains, a single speed chain may require regular cleaning and lubrication to maintain optimal performance and longevity. Overall, a high-quality bike chain master single speed is an essential component of a well-functioning single speed bike, providing the necessary power transfer and durability for a smooth and reliable ride.
