Rohloff Caliber 2 Chainwear Indicator - 3000

The Rohloff Caliber 2 is a precision made chain wear indicator. It allows the measure of chain wear in seconds & indicates if the chain is too worn for steel or aluminum sprockets/chainrings. After extended use, a chain will no longer fit correctly in the teeth of the sprockets, due to elongation & wear. If the chain is not replaced, then chainrings & sprockets may be damaged & eventually the chain will skip over the sprockets. The Caliber 2 allows you to quickly determine chain wear before your chain gets to this condition.
