TAYA, coating specialist, will plan to launch 8 speed e-bike chain “OCTO DH” for the brand new cycle year. Electric-powered drive system generates high torsion forces while starting up, city traffic further strengthen the impact on this issue. TAYA exclusive DHT heavy-duty chain provides most reliable solution to the trendy e-bike. Non-Negotiable Durability DHT (Diamond Hard Tech) presents the advanced durability enhancing treatment, DHT series chain has excellent performance in anti-elongation, and min. the wear of gear group as well. In Knoop hardness test, DHT treatment highly increased the hardness up to 1,800HK, 25% harder than the other chain in the market. Thus, the average DHT chain life raised 7,000KM depends on different product levels. Self-lubricated Feature Smooth shifting performance is the crucial function for derailleur system. DHT with self-lubricated feature creates low friction at gear shifts. In abrasion test, low friction results in low elongation rate and 3 times additional chain life! TAYA ¡¨Diamond Hard treatment¡¨ for e-bike has adopted on the new generation of 11-speed: eONZE, 10-speed: eDECA, 9-speed eNOVE series, and also on 8-speed chain eOCTO DH DHT Video on Youtube：http://youtu.be/o8EUeLwJuNA
