Project321's G3 157x12 Rear Hub

Our approach with G3 was to build a hub that strikes the ideal balance between strength, weight, reliability, and efficiency. The result of this design philosophy is a robust and efficient hub set with instant, rock-solid engagement.

Engagement

G3 hubs use the same 72 tooth drive ring and three-step magnetically actuated pawls as our proven G2 hubs. To increase engagement without compromising reliability we added two additional pawls instead of miniaturizing the teeth on the drive ring and pawls. A total of eight pawls work in teams of two, to give 1.25° or 288 points of engagement. We believe this gives riders the ideal balance of instant engagement and rock-solid reliability.

6-Lock

6-Lock is a new patent pending technology by Project321. 6-Lock is an enhanced six bolt design that features stainless steel bolt threads. No lockring is required, only T25 Torx hardware, giving the rider true six bolt rotor retention. 6-Lock easily converts to center lock, giving you unrestrained brake rotor optionality.

G3 Front Hub are made with aerospace grade 7075-T6 aluminum, one of the toughest metals for hubs on the market. All hubs come in 1 of 12 vivid colours and are fully anodized to look as good as they perform.
