Worlds first independent chain tensile strength testing!
Usually ZFC conducts the most robust testing to determine best products to stock & recommend vs which products do not live up to marketing hyperbole.
In this case, it is unknown if the testing will lead to any purchasing decision changes or recommendations or not, however I have been curious re chain tensile strengths for awhile now, and the industry now moves onto 12spd, it was time for a fun side test project. And one thing learned from lubricant and chain longevity testing, is that surprises always seem to come up, and these surprises have most definitely impacted on stock / avoid decisions.
