Technology

Innovative Bike Engineering From Germany Since 1893

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 on all derailleur systems.

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.

Features
