Have you ever dropped your chain pin while working on your bike in a makeshift garage, only to discover it has vanished into thin air? Or maybe you installed it incorrectly the first time? Fortunately, Shimano offers replaceable chain pins! These chain pins are compatible with their corresponding Shimano chains. Although it would be fantastic to find a single sock to match that lone sock at the bottom of your dryer, replacing lost or damaged chain pins is now a simple and stress-free process.
