The German magazine Aktiv Radfahren awarded the Herrmans Endorfin grip as their favorite option for city bikes in their test of ergonomic grips. The magazine states:
Cruicial for the Herrmans Endorfin grip is it s 3-component-fabrication in Europe and the pollutants free manufacturing. Mounting and dampening are the best in the whole test. Feeling and control are also on a high level. Pleasant: The rubber is not as sticky as on other grips. Equipped with a fair price and quite light the Endorfin is our City Tip.
