Those who expect the highest performance will find no alternative to Connex chains:
The optimised geometry of the plates enables extremely rapid and virtually silent gear
changes.
Highly developed Peripheral chamfering of the outer plate ensures optimum gear-changing performance. Innovative radial riveting of the pins, combined with a special pin coating, guarantees top performance and long wear, even under the high forces of cross gearing.
SPEED WING
Optimised plate design for rapid and quiet gear changes.
DIAMOND SHAPE
Innovative chamfering of the outer plate for quick and precise gear-changing and optimal chain guide
POWER PIN
Innovative radial riveting and pins with an extremely wear-resistant surface for highest resistance to wear and maximum strength
