Eliminate the guesswork.

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.

Easy to use, pays for itself quick

  • Familiarity: I've used it several times

This chain checker is easy to use to check your chain stretch. While I don't use it very often, it's nice to have to be sure I replace an inexpensive chain prior to needing to add a cassette or chainrings to the bill. Easily pays for itself in time when considering some 11 speed cassettes are upwards of $500. Construction is solid and like Ben said, will be the last one you ever need.

Well crafted chain checker

  • Familiarity: I've used it several times

This is easy to use and the tool is made very well. Pick one up and it'll be the last one you ever need.
