Performance without Compromise. G3 features instant rock-solid engagement, patent pending 6-lock technology, and more. Advanced M-Pulse Technology Designed for instantaneous power transfer and reduced drag. Unlike traditional spring actuated drive mechanisms, M-Pulse uses magnets to actuate the pawls—eliminating tiny springs that can be lost or damaged during servicing. This not only reduces drag, but also improves reliability and ease of maintenance. Instant Rock-Solid Engagement G3 features a 72-tooth drive ring with oversized teeth paired with magnetically-actuated pawls, providing rapid engagement and minimized drag while freewheeling. The incorporation of eight pawls working in pairs of two, results in 288 points of engagement (POE) and a precise 1.25° engagement angle. Foundation for Strong Wheels Optimized hub geometry to balance spoke tension, angled flanges for a more direct path for spoke and nipple, and tall flanges to maximize torsional stiffness make Project321 hubs the ideal foundation for incredibly stiff, responsive, and reliable wheels. 6-Lock Technology A new and enhanced six-bolt design featuring stainless steel thread and no lock ring, allows you to easily convert from six-bolt to Center Lock with only T25 Torx hardware. 6-Lock Technology gives you the versatility to run your preferred rotor system. Available with all stock G3 hubs. Updated Axle and Bearing Layout Fully anodized 7075 aluminum axles with two double row bearings at the highest stress points and fine pitch preload adjustment, delivers long lasting, smooth rolling performance under the most demanding conditions. Drive Ring Seal System Improved two piece seal system keeps oil in and contaminants out, through a new low-drag, light-contact rubber seal and aluminum dust shield. Maximized Compatibility Project321 Hubs are designed to make drivetrain and end cap conversions simple and straightforward. G3 features easily interchangeable drivers offered in HG, XD, and MicroSpline versions, universal end caps and bearing configurations across all drivers and axle sizers, and both 12mm and 15mm front end caps.
