The Birzman Chain Checker is an essential tool that quickly and accurately shows when your chain reaches 0.145% and 1% of wear. As a chain wears, shifting quality degrades and wear increases on the cassette. Many chain manufacturers recommend replacing a chain after 0.145% of wear. The Chain Checker is made from precision, laser cut steel.
