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.

G3Ti features a 72-tooth drive ring with oversized teeth paired with magnetically-actuated pawls, providing rapid engagement, minimized drag while freewheeling and strong enough for any existing or yet-to-come e-bike. Tested to peak torque of 1100 Nm without failure. The incorporation of eight pawls working four at once, results in 144 points of engagement (POE) and a precise 2.5° engagement angle.

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.

G3Ti is available in 6-Bolt and Center Lock interface to ensure simple and straightforward compatibility with e-bike speed sensor.

Fully anodized 7075 aluminum axles with three double row bearings at the highest stress points and fine pitch preload adjustment, delivers long lasting, smooth rolling performance under the most demanding conditions.

Improved two piece seal system keeps oil in and contaminants out, through a new low-drag, light-contact rubber seal and aluminum dust shield.

Project321 Hubs are designed to make drivetrain and end cap conversions simple and straightforward. G3Ti 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, 15mm and 20mm front end caps.

Colour match your hubs to add a personal touch to your build. With 10 vibrant colours offered, you can mix and match between shells, end caps, and 6-lock.

Rock-Solid e-bike approved engagement when it matters most.
