Bicycle Cotter Pin

Bicycle cotter pins, also called crank cotter pins, are essential for securing the crank arms to the bottom bracket spindle. Despite their small size, these components play a critical role in ensuring safe and efficient pedaling. Using the correct cotter pin size and properly maintaining it prevents crank loosening, drivetrain noise, and potential accidents. One of the most common sizes is the 9.5 mm crank cotter pin, widely used in traditional and classic bicycles. Made from steel and often coated to resist corrosion, high-quality pins provide durability and reliability. Installing cotter pins correctly ensures the crank arm stays firmly in place, even under heavy pedaling or rough terrain conditions. A bicycle cotter pin removal tool is recommended for maintenance or replacement. This tool allows precise removal and installation of cotter pins without damaging the crankset or spindle. Regular inspection of cotter pins helps identify wear, rust, or bending, ensuring the bike remains safe to ride.

Investing in quality cotter pins and proper tools enhances bike longevity, improves performance, and ensures a safer, smoother cycling experience.
