Looking into High Test Myth
High-strength G70 chain appears ideal—so what’s the catch?
In recent years, our chain tests (see PS September 2006, July 2007, July 2008, and October 2012 online) were limited to G30 and G43 (high-test) chain. Our conclusions were pretty straightforward: We would avoid stainless steel for several reasons, the most persuasive being its tendency to fail without warning—as our test sample did. Recognizing that corrosion is what ends the life of most chains, we were not convinced that shelling out more money for the extra strength of G43 chain made sense. It lasted no longer than G30.
