Chainwear Results Chart

Chain Wear Test Methodology:

Each chain was measured at the intervals shown on the chart and its length recorded. Testing ended when the subject chain "stretched" by 1%*

*Note, Chains don't "stretch". They get longer as pins wear against rollers; this phenomenon is commonly called "stretch". Once a chain stretches by 1%, it should be replaced. Worn chains cause premature wearing of cogs and chain rings and don't shift or transmit power as efficiently as when new.
