Foundation Bike Hand Chain Wear Indicator Tool

Very few things on a bike make as big of a difference as replacing a worn chain at the correct time. Replacing a chain at the optimal time before it’s excessively worn prevents unnecessary wear on more expensive cassette and chainring components—not to mention maintaining those crisp shifts! The Foundation Chain Wear Indicator Tool is a precision instrument for measuring the level of chain wear to both 0.75% and 1%, letting you know the exact time when chain replacement is needed. The reliable construction of the tool provides you with accurate readings every time, while the minimalist design is easily tucked away in a tool drawer for quick access.
