1. Every manufacturer recommends replacing the chain at slightly different tolerances, but a good rule of thumb is to install a new chain if there is excessive chain slack and stretching. Consult your owner’s manual for exact specifications. 2. Replace the chain if you notice damaged rollers, loose pins, kinked or binding links, or excessive wear. 3. Always install a new chain when installing brand-new sprockets. Failing to do so will cause the sprockets to wear out much quicker. Replace the drive sprocket, rear-wheel sprocket and drive chain as a set. KNOW WHEN IT’S TIME TO REPLACE YOUR CHAIN
