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.

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.

The advantage of using a foaming chain lubricant is that, unlike an oil
bath, you don't have to remove the chain and soak it.

With an oil bath, it does help to heat the oil slightly if you want to
speed up the process.

I have tried doing an "oil bath" with one of those chain cleaning tools
filled with non-detergent oil instead of solvent. It works, but it's
messy and probably no faster than removing the chain, since you need to
move the chain through the oil pretty slowly.

With the new thinner chains, you want to minimize removing them unless
they have a connecting link and don't require a rivet extractor.

My goal is to minimize the time and expense of chain maintenance. A
chain cleaning tool used with kerosene or diesel fuel as a solvent, and
a can of non-O-ring foaming chain lubricant gets the time down to just a
few minutes. I have no interest in recreational chain maintenance.

Then I do everything wrong:
- use wax base lube,
- don't use a torch, just drip the stuff on every roller,
- never take my chain of the bike,
- never clean it with nasty solvents.
Rode last Sunday more than 2 hours is a down pour. My chain didn't squeak after the wetter improved. Came home and hosed my bike with the garden hose. Wiped my bike and chain dry, put it in the stand and lubed my chain the next day.

Well **** it, a chain life of 8000 km is good enough for me...

From top to bottom: new chain, chain lubed with my wax based lube and chain lubed with Rohloff chain oil for a while. Both chains had a milage of 8500 km. Yes, Mike, Sheldon and Jobs had it wrong sometimes IMO. But if you happy with your foaming lube that is OK, but don't tell me that I have to spend a lot of time on chain maintenance to get a long chain life. You are losing your credibility.


I do basically the same thing with my 11sp chains after a long ride in the muck and rain -- put the bike on a wash stand, hose it down and suds it up a little with Simple Green, clean the chain and cassette with a stiff brush while turning the crank. Rinse fully (Simple Green is acidic). Wipe it all down and relube the chain. Pamper, preen, put bike away in basement shop..

Procedure with my 9sp commuter is: lean bike against inside garage wall, go inside, dry off and eat dinner. Oil chain next day with whatever is hanging around the garage door -- maybe wipe a garden slug on the chain, spit, WD40. I might actually take the chain off that bike and give it a soak because the links are reuseable.
