Eliminate any guess-work with this handy chain roller wear measuring tool. Simply put the wrench-side on a chain roller and use the measuring gauge to determine if the chain needs to be replaced. Measure at several points of the chain since these tend to wear unevenly. Replacing the chain in time will often safe you from replacing the sprockets too.
