Merida Matts TFS 600 original chain lube What lubricant does the chain of a Merida TFS 600 bring from its factory?
Typically, a chain uses a grease lubricant which is applied hot to the chain into every crevase of the chain before the chain is assembled. Its generally the best lube you can get on a chain, but its impossible to apply at home in the same way (contrary to sheldon brown) [aside from the fact that that particular formula is likely not sold]. Some more details from Shimano are here.
