Crafted from premium materials and featuring advanced engineering, this hub is optimized for high-speed stability and smooth engagement.

Materials & Construction

Built with anodized 7075 aluminum axles, the G3 6-Lock hub offers exceptional strength and corrosion resistance while keeping weight to a minimum. Its durable construction incorporates two double-row bearings at the highest stress points, ensuring reliable performance under rigorous riding conditions. The hub’s black finish provides a sleek, tactical aesthetic that complements any bike frame.

Performance & Engineering

Experience near-instant engagement thanks to the innovative 1.25 /288-point engagement system. Eight 3-step pawls, phased in pairs on a 72-tooth drive ring, deliver a crisp, rock-solid feel with minimal play. The magnetic pawls increase pull strength as they engage, reducing drag during coasting and enhancing efficiency on every pedal stroke. The absence of springs and reduced moving parts mean less maintenance and increased durability.
