YBN took two years to explore the Ni-PTFE Teflon Coating, and made the "SLA" Superior Lubricating Aid series. Less Friction, Smooth, Noiseless and Easy cleaning are the main characteristics of SLA chain series. The Durability of the SLA series are upgraded 200% by these characteristics. SLA Superior Lubricating Aid series no need to grease heavily, slightly greased after cycling will be fine.
YBN has been using the DHA Chromium Carbide Surface Hardened Treatment to increase the hardness of chain pins. Excellent performance can be expected even in adverse conditions, including the presence of abrasive contaminants. Furthermore, DHA pins is also anti-rust. DHA Chromium Carbide Surface hardened pins are able to prolong 100% of lifetime. The chains are not prolonged easily
