Unior's Manual Chain Wear Indicator provides quality assurance with its Go/No-Go gauge. If the tool fits, it's a "Go"; and vice-versa. Insert the two ends of the tool into your chain and push down gently. If you can get the tool to drop over the chain on the 0.7%-1.2% side, the chain is worn and should be replaced.
