[QUOTE="Jaybird, post: 657412, member: 22283"] Dave is correct about the materials being used for O-ring chains these days. Some still use inferior material for the rings and certain chemicals can attack the rubber. Top shelf chains are using Viton or simialr materials for the rings. These rubbers can withstand some chemical attack. Also, you CAN benefit from lubricating a dirty chain. The thing is, you need to be applying the proper type lubricant if you do this. Penetrating dry-film type lubricants are carried by a solvent and this solvent cleans as it is applied. I'm not talking about cleaning the visual part of your chain, I'm talking about the microscopic asperities, or craters, in the metal's friction surfaces. If you use a lube that utilizes lubricating solids for the EP additive, these solids tend to be polar and will then adhere to the just cleaned craters. The solvent carrier then will evaporate, so the treatment doesn't attract more dirt. I won't go too much into brand specifics since I'm obviously biased, but on WD-40...We have Timken lubricity test machines and have tested just about every major brand of lubricant on the market. WD-40 is one of the least impressive fluids we've tested. Sure, it is clean and has dry-film charectoristics, but it falls way short on lubricity. There are far better choices, albeit them not as easy and cheap as the wonder fluid. I know lots of you love the stuff, but I wouldn't suggest it's use to anyone. It's a water dispersant/light lubricant, people. Not a lube designed for our sport. :) One more thing for o-ring chains....you need to lube them to keep the o-rings supple, however they also need to be lubricated to protect the roller/bushing friction area and the roller/sprocket friction area. Neither of these areas are lubricated at the factory, they depend on you to keep them clean and lubed. [/QUOTE]
