Not only runs smoothly, but also fast

In the world of road bike, every watt of power waste is unacceptable, so we decisively chose the new system, and we also divided them into two groups to make it reach 72 click/round. 36T x 2 Group
Upgrading from 4 pawls to 6 pawls
Super smooth pawls system

Why we chose the pawls system instead of the ratchet system this time?
We need to emphasize again that this is not an normal pawls system.
Our experiments shows that the 36T ratchet system has approximately 1.47N rotation resistance,but our new 4 pawls system as approximately 0.343N rotation resistance. It means that the running resistance of the hub body has dropped by 76.6!
