Anyways... routine lubrication is good. Strict cleanliness plus lubrication is great.
I agree, cleanliness is critical, but I reiterate the importance of the grease inside the bearings of a chain. This is less my quirky suggestion, than the service suggestion of every major chain manufacturer. Shimano, SRAM, KMC and Campagnolo are unanimous in advising riders not to 'degrease' chains in solvent. For the reasons I stated above.That said, in some situations the greaseless chain is less a problem than in others, but as a general rule it should be avoided.
