Last Updated on July 2, 2023 by FAB Jim The Cyclist

If you do a lot of cycling, eventually you will wear out your chain.  This is a great tool to tell you when it is ready to be replaced.  It is simple and easy to use and it’s not that expensive.  Have a look:

Park Tool CC-3.2


Made of silver alloy

Compatible with most 5-12 speed chains

Gauge indicates .5% and .75% or more wear.

How to use

This is very simple to use.  You put the side with the rounded hook into your chain and see if the other end will fit into the chain.  If it doesn’t fit your chain is fine.  If the 0.5 side fits your chain, it has .5% wear.  If the 0.75 side fits your chain has .75% or more wear.  Here is a guide for when to replace your chain:

0.5%: replace if you have a 11 or 12 speed chain.

0.75% or more wear: replace your chain.


5 out of 5 stars.  Great simple tool to gauge when your chain needs to be replaced.  Get yours today on Amazon.

  1. I wish I had the skills to fix my own bike. I always take it to my bike guys shop at the end of the season, he does whatever to maintain it for me.

  2. Or better yet for me just buy a new or used Huffy bike when parts start breaking down. Thanks for the simple chains tip.
