RG3 Road Center Lock Front Hub

Project 321’s RG3 Road Center Lock Front Hub is built for road and gravel wheel builds where rotor interface accuracy and long-term reliability matter as much as low rolling resistance. Shipped with a Center Lock brake mount and produced in Canada, it’s a premium choice for riders who want a clean, serviceable front hub to match modern disc road and all-road setups.

Key details for road + gravel builds

• Center Lock rotor mount - Clean interface and straightforward rotor installation for modern disc road and gravel wheels
• RG3 platform compatibility - Ideal for matching a complete RG3 wheel build; the RG3 system is known for M-Pulse magnet-sprung pawls designed for ultra-low drag and fast engagement on the drive hub
• Upgradeable to 6-bolt - Ships Center Lock, with the option to convert using the 6-Lock assembly when a 6-bolt rotor standard is preferred
• Road and gravel intent - Designed for mixed-surface use where consistent tracking and brake alignment support confident cornering and braking
• Made in Canada - Built with tight process control and traceability riders expect from a high-end, small-batch hub
