Regina HPE High-Performance-Endurance Maintenance Free 520 Gold Chain

The Tetrahedral Amorphous Carbon (ta-C) coating, currently considered as the most advanced among DLC (Diamond Like Carbon) coatings, applied on the surfaces of the bushings and the rollers of the HPE Chain, combining high hardness with a low coefficient of friction

• eliminates the need of periodic re-lubrication, while ensuring at least the same mileage obtained with a normal chain regularly lubricated every 500 km
• reduces energy dissipation and increases efficiency in the chain drive
• eliminates lubricant spatter during operation, minimizing environmental impact.

ta-C: THE CARBON COATING CLOSEST TO DIAMOND

Pure Carbon is present in nature only in two crystalline physical states: Diamond (atoms in Tetrahedral bonding arrangement) and graphite (atoms in Hexagonal Planar bonding arrangement).
ta-C is a synthetic state of pure Amorphous Carbon in which up to 80% of the atoms are bonded to each other with a Tetrahedral arrangement, in the same way of pure Diamond. For this reason, among all so called “DLC” (Diamond Like Carbon) coatings, the physical properties of ta-C (such as hardness & coefficient of friction) are the closest to pure Diamond, which is the hardest material on Earth.

HPE CHAIN INSTALLATION

• a chain drive using an HPE Chain does not require ta-C coated front and rear sprockets
• when installing a new HPE Chain, it is strongly recommended to replace front and rear sprockets with new ones. Sprockets must be made of steel

HPE CHAIN MAINTENANCE, CLEANING AND TENSIONING

To guarantee its best functionality and aesthetics over time, follow 3 simple rules:

• clean and re-lubricate the chain
  • after washing your bike
  • after using your bike in wet conditions and / or in salty or dusty environments
  • before storing your bike at the end of the riding season (winter season)
• re-lubricate the chain once a year
• check correct chain tensioning every 3.000 Km.
