XLC TO-S82 Chain Wear Gauge

The TO-S82 bicycle chain wear indicator is the perfect item to establish when it is necessary to change the chain . As you pedal the chain stretches over time. If you stretch too far, the gears on your bike will start to jump, creating a horrible jerking effect. The gears won't shift as smoothly, and you even run the risk of breaking down completely if left on too long. This chain wear indicator is very simple to use: place the curved end in a gap between the chain links and allow the other end to fall gently into contact with the chain. If it falls through a gap without contacting another link, so that the long part of the tool lies flat along the chain, your chain is worn and could use a change.
