Specifications

Upgrade your bike's performance with the Project 321 G3 6-Lock Disc Rear Hub - the perfect choice for serious cycling enthusiasts and endurance riders. Designed for versatility, durability, and smooth engagement, this high-end hub features advanced engineering and premium materials to elevate your riding experience.

Materials & Construction:

Crafted from durable anodized 7075 aluminum, the G3 6-Lock rear hub offers exceptional strength-to-weight ratio and corrosion resistance. The hub incorporates high-quality double-row bearings at critical stress points, ensuring longevity and consistent performance in demanding conditions.

Performance & Engineering:

Experience lightning-fast 1.25 engagement with 288 points of contact. The hub's innovative 8-pawl, 3-step engagement system on a 72-tooth drive ring delivers an instant, rock-solid connection when you start pedaling. Pawls are magnetically driven, pulling harder as engagement nears, which reduces drag during coasting and eliminates traditional springs, resulting in a quieter, more reliable system with fewer moving parts.

Components & Technology:

The G3 6-Lock features an improved six-bolt system, offering seamless compatibility with Center Lock disc rotors for versatile braking options. The 28-hole J-bend spoke configuration ensures robust wheel building and reliable long-term performance. Additionally, the hub's fine pitch preload adjustment allows precise tension for optimal wheel tension and durability.

Style & Use Case:

Built for mountain biking, trail riding, and gravel adventures, the silver finish gives your bike a sleek, professional look. Compatible with 12x148mm thru-axles and designed for rear wheel setups, this hub is ideal for riders who demand smooth engagement, durability, and ease of maintenance in rugged terrains or high-intensity rides.

Innovative Features & Differentiators:

Instant 1.25 engagement via magnetically driven pawls for responsive power transfer

Fewer moving parts-no springs, minimal wear, and reduced maintenance

Anodized 7075 aluminum axle with preload adjustment for a customizable fit

Compatible with Center Lock rotors, enhancing braking flexibility

Made in Canada, ensuring top-tier craftsmanship and quality standards

Elevate your bike's rear wheel setup with the Project 321 G3 6-Lock Disc Rear Hub - engineered for precision, durability, and high-performance riding. Optimize your drivetrain with this premium, innovative hub designed to deliver instantaneous engagement and reliable service on every ride.
