FEREI’s Magnetic Coupling Ratchet (FCT) elevates the traditional mechanism with higher precision, greater load capacity, and a simplified, more convenient ratchet-ring replacement. Riders can switch between different tooth counts as needed.
Built on the magnetic coupling system, the upgraded version features a larger ratchet ring with 48 or 72 teeth, delivering faster and more responsive power engagement. The expanded ring also allows the drive-side bearing to move outward for stronger structural support, forming a fully enclosed, dust-resistant interface. The enlarged ring further enables a bolder, more powerful flange design that enhances both performance and presence.
