BBB chain gauge Chainchecker BTL-125
Useful tool for easily checking the wear condition of the chain, because changing the chain early protects the chainrings and sprockets. The Chainchecker is suitable for all standard derailleur chains! The BTL-125 also has some useful additional functions such as the chain hook, which makes it much easier to fit and remove the chain.
When the elongation reaches 0.75 = 75%, the chain should be replaced.
If the elongation reaches 1.0 = 100%, the chain must be replaced immediately! Because it is completely worn out!
