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.
