American industry nine i9 flower drum Industry nine is "King" in the tower base. Its six claw 120 point engagement transmission mechanical structure is the industry leader and the most outstanding design at present. The tower base of the flower drum flywheel is made of 7068 aluminum alloy, whose strength is 20% higher than that of 7075. At the same time, the tower base is designed with 3 bayonets. Each bayonet has 3 high-precision bayonet points, with a density ratio of 120 (higher than King's 72). In this way, when the tower base of the flower drum rotates, the rear flower drum of a one-way driving component every 3 degrees makes the trampling kinetic energy pass through the chain to the drive of the rear wheel with zero loss, making the sprint and uphill lighter and stronger.
