The M-netic hubs are the latest product by SOUL-KOZAK. M-netic is a revolutionary ratchet gear system using annular magnets whose magnetic force allows a ratchet ring to engage the cassette body with even force.

The M-netic system is innovative design of SOUL-KOZAK’s owner and head engineer, Mariusz Kozak.


M-netic is used in new generation ROAD and MTB hubs. The invention of M-netic system allowed to create a failure-free rear hub; lack of pawls and springs made the design much simpler as it consists of much fewer parts, and the decreased weight of the new design allowed the use of much tougher bearings.


Extensive tests proved that the M-netic system is perfectly reliable, even in muddy and wet conditions and at high torque. The M-netic rear hub is a reflection of SOUL-KOZAK’s advanced technologies and care for details.

Compared to the classic rear hubs with small pawls and springs which are sensitive to fatigue, dirt and moisture, M-netic is much more reliable, lighter, capable of managing higher torque, and the cassette is engaged faster and more smoothly. Unlike the spring-mounted pawls, magnetic field does not corrode. Also, dirt does not diminish the effectiveness of the entire system and does not increase parts wear. Sturdy and tough engaging teeth on the ratchet ring and the cassette, which are made of properly heat treated steel, provide failure-free action of the drive device. M-netic rear hubs consist of fewer parts and their servicing is very easy.
