Description

• Tensile strength increase: A slight jump from the ERV3, the ERV7 boasts a 3% higher tensile strength due to stronger inner side plates and thicker pins • Longer chain life: Due to increased X-Ring durability, the ERV7 chains see a 13% wear resistance increase from the ERV3 series • Reduced friction: Because of the X-Ring improvements the ERV7 will have less friction than the ERV3 series • Wear life index: 3500
