What are the benefits of the new hub vs. the old Cognition hub?

Cognition hubs with Axial Clutch technology reduce drag by disengaging the ratchet mechanism when coasting. The Axial Clutch uses Sylomer (an advanced material used in a variety of hi-tech industries) to create a wave spring that re-engages the rings when the rider starts pedaling. The new system is simpler and quicker with 54 points of engagement, reducing overall friction for a smoother ride.
