Regina 525 HPE Z-ring chain 124 Links

Regina introduces the innovative and revolutionary High Performance Endurance (HPE) Z-Ring chain, which only requires periodic lubrication every 1000 km. Extensive laboratory and road tests show that the service life of the HPE chain is at least equivalent, if not longer, than that of traditional regularly re-lubricated Z-Ring chains.

A hydrogen-free tetrahedral amorphous carbon (ta-C) coating, currently considered the most advanced among DLC (diamond-like carbon) coatings, coats the surface of the HPE chain bushings and rollers.
The Ta-C coating reduces energy dissipation and increases secondary transmission efficiency by combining very high surface hardness with a low coefficient of friction.

Includes:

• Chain.
• Chain joint.
