Barbieri Chain wear indicator Bike Hand

The Bike Hand tester allows for a quick and accurate examination of a bike chain's wear level. Simply place the tester between the rivets to determine the extent of the chain's deterioration when it is slack. If the hooks on either side fit easily into the chain, it means it needs to be replaced.

There is also a tester with a chain holding system. This chain checker BIKE HAND shows the wear of a bike chain according to two levels: immediate replacement or chain nearing the end of its life.
