Specifications

Upgrade your cycling performance with the Project 321 RG3 Road HGR Center Lock Rear Hub, engineered for endurance, speed, and reliability on both road and gravel terrains. Crafted from high-quality materials, this hub features lightweight yet durable aluminum construction that ensures optimal stiffness and longevity under demanding riding conditions.

Materials & Build:

Constructed with precision-machined aluminum alloy, the RG3 rear hub offers a perfect balance of strength and weight savings. Its black anodized finish provides corrosion resistance and a sleek, aerodynamic look that complements any bike aesthetic.

Performance & Engineering:

Designed for riders who demand instant engagement and minimal resistance, the RG3 uses M-Pulse magnet sprung pawls-providing ultra-low drag with lightning-fast power transfer. The 28H spoke hole configuration with J-bend spoke profile ensures precise wheel-building and durability, making it ideal for aggressive road and gravel riding.

Components & Technology:

Equipped with a Center Lock brake mount for straightforward, secure disc brake installation, this hub offers seamless compatibility with standard Center Lock rotors. The hub features a 12x142mm rear axle spacing with a robust construction designed for reliable power transfer and axial stiffness. The hub ships with a standard Center Lock interface but can be upgraded with the optional 6-Lock assembly for riders preferring 6-bolt system options.

Style & Use Case:

Designed for serious cyclists seeking versatility and performance, the RG3 Road HGR Hub excels in gravel adventures, fast-paced road riding, and endurance events. Its sleek black finish and precise engineering make it suitable for high-performance wheelsets or upgrading existing wheels.

Innovative Features:

Made in Canada, the Project 321 RG3 hub emphasizes craftsmanship and quality control. Its magnet-sprung pawl system sets it apart from competitors, offering not just low drag but also consistent engagement and long-lasting precision.

Third-party sales via platforms like eBay and Amazon are strictly prohibited by the manufacturer to maintain product integrity and support.
