Regina launches lube-free Z-Ring HPE chain
The magic ingredient is a hydrogen-free Tetrahedral Amorphous Carbon (ta-C) coating, currently considered to be the most advanced among DLC (Diamond Like Carbon) coatings, often used on front forks, that is applied to the HPE chain bushing and roller surfaces.
"The ta-C coating reduces energy dissipation and increases efficiency in the secondary transmission, combining the very high hardness of the coated surface with a low coefficient of friction. The elimination of chain cleaning and lubricant spatter during operation minimises environmental impact.
"The innovative ta-C coating process was developed through intense R&D activity by Regina engineers and is entirely carried out in our Cernusco Lombardone (LC) plant in Italy [between Milan and Bergamo].
"The elimination of the periodic re-lubrication and the greater efficiency of power transmission raise the HPE chain to an extremely advanced technological level compared to traditional sealed chains - unthinkable until today and unparalleled on the market," said Paolo Garbagnati, CEO of Regina.
"We would like to thank all the women and the men who made the achievement of this important goal possible, including all the passionate riders, who, confidentially and professionally, contributed to the project with many extensive test rides." The HPE chain will be available on the aftermarket starting January 2021 and works with the same front and rear sprockets used with traditional sealed chains.
