Description |

Project 321 G3 Rear Hub 12x142 is built to balance strength, weight, reliability, and efficiency, with instant, rock solid engagement. The G3 uses a 72 tooth drive ring and a three step magnetically actuated pawl system. A total of eight pawls work in teams of two to deliver 1.25 degree engagement, or 288 points of engagement.

For braking, the G3 uses Project 321 6 Lock, an enhanced six bolt rotor interface with stainless steel bolt threads. It uses T25 Torx hardware and does not require a lockring for six bolt rotor retention. It can also be converted to center lock, with the note that external spline lockrings must be used for center lock rotors.
