To achieve ultimate efficiency, Driven utilises 21 CeramicSpeed hybrid bearings. Each bearing contains unique ceramic balls that are 58% lighter and 2.3 times harder than traditional steel, increasing the speed of the bearing by 30-50%. Each bearing works in harmony to deliver greater power, playing a pivotal role in performance and speed.
