The e-bike version in the standard PP 12 × 148 was born from the EXTREME hub for Gravity use. We wanted to develop a hub dedicated to E-bikes designed to withstand the greater power deriving from the electric motor. We have reinforced the structure of the hub and introduced a free wheel with 4 ratchets with a single spring under each of them. The ring is 36 teeth to reduce the angle of engagement and have a always ready response. The front hub has not been changed from the Extreme version dedicated to gravity disciplines.

Hubs use oversized high quality bearings. The wheel’s smoothness is directly proportional to the bearing quality and endurance level of hub parts. Large bearings perform better under static and dynamic loads, offering longer service life and reduced rolling resistance.
