The pins and rollers are made from steel. I don't see how PJ1 can penetrate solid steel unless you also prefer to ride on sintered steel or steel sponge (if there is such a thing). The promo page (first URL above) also says: "After penetrating the inside of the chain, the lube becomes a sticky lubricant that bounces back or has a "memory" effect that withstands the continual mechanical stress of the chain." Oil is incompressible and does not bounce. If you want a good simulation of how bouncy oil works, fill the brake lines of your car with air bubbles and try using the brakes. Kinda looks like the stuff was made for motorcycles, not bicycles: "Specially optimized for a standard non-O-ring chains, yet is O-Ring safe and compatible with either type of motorcycle chain." This one is great: "New super tacky formulation reduces dirty fly-off, displaces and repels water, protects against rust and corrosion, extending sprocket and chain life." In other words, it's super sticky and both collects and attracts dirt. In my never humble opinion, the product might be good for motorcycle chain, but is probably the same as chainsaw bar oil for bicycles. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Hmm, who do you want to believe long-time bicycle shop owners & expert bicycle mechanics, chain experts, and Jobst, or Frank? Tough decision--not. What the Experts say About Chain Waxing: "When wax was popular, we'd get customers coming in all the time complaining about shifting problems on their bikes. Removed the wax and lubed with conventional stuff and voila, shifting back to normal." Mike Jacoubowsky, co-owner of Chain Reaction Bicycles. "Wax is not mobile and cannot return to a location from which it has been removed by rotation of one part on another." Jobst Brandt, author of The Bicycle Wheel "If you use dry lube or wax, follow product directions and use it often. In some cases, dry lube should be used for every ride. It wears off very quickly and no new lube can flow to the critical wear areas." Craig Metalcraft, manufacturer of Super Link III. "Downsides of the wax approach include the fact that it is a great deal of trouble, and that wax is probably not as good a lubricant as oil or grease."

That's why this observation "If you use dry lube or wax, follow product directions and use it often. In some cases, dry lube should be used for every ride. It wears off very quickly and no new lube can flow to the critical wear areas" is especially relevant. Or as one manufacturer states "As the foam breaks, the lubricant penetrates into wire rope and roller chain mechanisms, depositing a molybdenum disulfide based grease to provide superior lubricating properties to surfaces." I don't think it should surprise anyone that the best lubricant for a chain is a lubricant designed for a chain. |

But out of curiosity can you comment on exactly what this foaming solvent is? Who makes it? Where it can be obtained? I ask as we were using grease and heavy oils diluted with a volatile thinner to lube crane lift cables at least 40 years ago and I don't believe that it was a new process even then, while you appear to be describing something that is NEW and BETTER, apparently because it foams? Another thing that is puzzling is that while you are recommending this remarkable foaming stuff and don't actually say so your language seems to hint that without foam it just won't penetrate into the chain links yet I have worked on chain driven equipment with chains that were ten or more years old. Still perfectly usable and no foam at all. Just a SAE 40 oil bath. So the question is, is foam really necessary? By the way, here is a company that makes wax lubrication for industrial use as a chain lubricant. https://www.klueber.com/en/lubricant...icating-waxes/ In fact they write: "Dust, dirt and lint influence the function of your chains in the long run. Our lubricating waxes protect this important component against contamination and premature wear. They should also be your first choice for chains in frequent contact with humidity." "Our lubricating waxes for chains, for example Klüberplus SK 11-299, are applied via warm immersion baths. Once dried, the lubricant protects your component for an extended time, sometimes even for the entire lifetime of the chain." I find it strange that a company manufactures a wax specifically to lubricate chains while a group of people, apparently with no experience in the field are shouting "won't work!" -- Cheers, John B. |

Still perfectly usable and no foam at all. Just a SAE 40 oil bath. It is easy to penetrate a chain. The lube just has to have a low enough viscosity that is all. Thats why wax based lubes have some volatile component. The cheapest is iso propanol. Oil has a low enough viscosity of his own. So the question is, is foam really necessary? Of course not. Lou |

Mike and Sheldon both worked at bicycle shops (Mike owns a shop) and if they take the time to explain the issues with hot waxing I think they are worth listening to. Jobst had a lot of opinions of course, but most were based on facts and logic, something that trumps the emotional feeling of hot waxing. Of course the trend now appears to be to mix hot wax with some sort of oil. Once the wax hardens and is displaced then at least the oil is still providing lubrication, but the wax is not, and there's less oil than if you just used oil alone. If you eliminate the wax from the mixture of wax and oil then it would be fine to hot wax. The hot oil is thinner than cold oil and will penetrate inside before cooling and thickening. Similar to how the foaming chain lube is thin when it comes out and thickens as the carrier evaporates. The two key things in chain lubrication a 1. Ensure that the lubricant doesn't just remain on the surface but penetrates into the pins and rollers. It needs to be thin to do this. 2. Ensure that the lubricant is not quickly displaced. Solid lubricants like wax are not suitable unless you could rig something up that keeps the chain hot and the wax fluid. Maybe this butane torch https://www.harborfreight.com/butane-micro-torch-63170.html keeping the chain hot. |
