Buying advice

When choosing a gear stock or pinion wire, consider the compatibility with your drivetrain, material hardness, and intended use (budget, racing, or high-speed). Higher-grade steel and precision-ground teeth improve durability and efficiency but cost more. Match the pinion size (5mm or 5.2mm) to your gearbox and weigh price against performance needs.
