Fresh chains shift better, but if you're not sure if yours still qualifies, the Unior Chain Checker is here to help. Built out of precision laser cut steel, this little beauty reliably tells you whether your chain is fresh and ready to roll, or stretched and ready to destroy your expensive cassette. The Unior Chain Checker is available in one size, and in one color.
