Connex Chainring Wear Indicator

Our chain ring wear indicator allows you to check whether you need to replace the chain ring or the sprocket to protect your chain. It is fast and simple to use and compatible with all geared drive chain rings and sprockets conforming to the standards. If there's a gap between the indicator and the chainring, you're good to go. If it sits between the teeth with no gap, it's time to replace the chainring.
