What Our Gearhead Experts Are Saying: "I keep these on hand so a worn pin never slows down chain work. They drop right in and restore smooth, centered engagement immediately."When a chain tool starts to lose its smooth feel, the pin is usually the culprit. The Decade Chain Pin Pair gives us a simple way to restore precision and keep chain installs clean and controlled. Swapping in a fresh pin helps maintain proper alignment with chain rivets and extends the working life of the tool, making this an easy addition to any well-organized workshop.
