This lubricant can quickly penetrate into every tiny gap in the bicycle gear chain, thereby eliminating abnormal noise and achieving a longer-lasting lubrication effect. Using refined mineral oil as a base, this oil can effectively reduce friction loss and noise, while preventing the chain from being corroded by external dust, ensuring that the chain is always clean and smooth. This product is not only suitable for bicycle gears and chains, but can also be widely used in door and window tracks, hardware tools, sewing machines, vehicle components, fan shafts, industrial gears, and household appliances.
