The Michelin Power Endurance is Michelin Pro4 Endurance’s successor. The Power Endurance has been improved in every aspect. 200.000 test kilometers and almost 5 years later Michelin finished their tyre that takes durability to another level. The puncture resistance has been improved with 20% by using aramide in the breaker layer. This tyre lasts longer than the Pro4 Endurance, has a lower rolling resistance and more grip in the corners. If you use both the front and rear tyre, 8.6 watt is saved on rolling resistance compared to the Pro4 edition.
