Regina 525 HPE High Performance Endurance Chain

HPE: SERIES CHAIN (HIGH-PERFORMANCE ENDURANCE)

• Tetrahedral Amorphous Carbon (ta-C) coating is an advanced DLC (Diamond Like Carbon) coating 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 for periodic re-lubrication, while ensuring at least the same mileage obtained with a normal chain regularly lubricated every 310 miles
• Reduces energy dissipation and increases efficiency in the chain drive
• Eliminates lubricant spatter during operation, minimizing environmental impact
• More power to the wheel
• Money savings on lube, fuel consumption and bike cleaners
• Combines high hardness with a low coefficient of friction
• For use with steel sprockets only.

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.
