HIGH PERFORMANCE ENDURANCE
THE FIRST MAINTENANCE FREE 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.
