Finish Line Teflon Synthetic Grease

Product Information

Shimano is the primary wheel manufacturer that uses cup and cone. MOST others do not. Please update your own knowledge base. In addition Shimano bearings do not use grease to ‘hold them in place.’ So that argument is worthless again.”

Criterion 5 – Keeping stable structure and hardness for a longer period of exploitation. Re-lubing bicycle bearings more often than once a year is highly impractical. Zero data to show the actual properties of the actual greases to washout or corrosion inhibitance even though it is listed as a requirement. Loads, even with MTB jumps, are not the problem with bicycle bearings – their number one nemesis is the dirt intrusion (even more than water washout, except for very wet/salty conditions). NLGI 1 hardness will do the job just fine. Having said all this – there’s nothing wrong with NLGI 1. Loads that bicycle bearings take do not require NLGI 2 grease. The most important thing is regular service (and dirt intrusion prevention – but that’s down to the bearing / hub manufacturer mostly). Serious levels of conjecture given here. I have to applaud the amount of conclusions made about which greases are suitable with zero science to support it.

Are you serious? THE ENTIRE ARTICLE the first thing you list in each type is water resistance. Literally. Yes there’s variation between each exact formula but no, lithium soap is lithium soap. It washes out.

There are thousands of different products – article was aimed at providing some guidelines, with “rule of thumb” properties. Motul and Mobile, to name a few, make some exceptional quality greases (and sell them at premium/higher prices). Placing the disc caliper behind the fork (a copy of a common design used in motorcycling) results in the braking force trying to pull the hub out of the flanges – downwards. People’s reactions to this particular article seem to range from taking it as a gospel, to taking it as blasphemy. Still – it is no more, and no less than: “what I have learned (through theory and practice) so far”. And, like all the other articles, it gets updated as new knowledge is acquired. Same as lithium complex greases with EP (extreme pressure) additives. In fact, lithium complex greases are almost impossible to find manufactured without EP additives. These additives are not needed for bicycle bearing use. With greases, all that is not needed is usually harmful, but in this particular case, no measurable harm comes from the EP additives. They can increase corrosion of coloured metals and silver, but with steel bicycle bearings they are mostly harmless™. Better without them, but no problems with them.Special greases with added solid lubricants, such as graphite, or molybenum disulfide (MoS 2). Usually used for high load and pressure bearing greases. Special additives, when they are notneeded, in addition to increasing the price, can have a negative affect on grease properties for the intended use! Some (many?), even well renowned, manufacturers don’t state ISO, (n)or DIN standards, but make claims about superiority of their products. Even such greases (of renowned manufacturers) are usually of relatively high quality and do the job they are meant for very well. I prefer to pay less for the same/similar quality AND know exactly what I’m getting for that money. However, it would be unfair to say that the companies you noted don’t make good greases: one wouldn’t do wrong with Phil Wood, Bel-Ray, or Shimano, just to name a few.

Greases where PTFE isn’t an additive, but a soap (or combination ofPFTE/PFPE soaps), that keeps base oil in suspension. Harder to find, more expensive, less compatible to mixing with other commonly used greases (see paragraph6.). Apart from that, characteristics are good for lubricating bicycle bearings. For coaster brake hubs (hub brakes) – good choice are greases that can withstand high temperatures (generated when braking). Lithium-complex soap based greases, or (if not sparing money, or they are already at hand) – lithium complex with molybdenum disulfide (MoS 2). Furthermore this entire series has been a showing of just how stubbornly ignorant you are toward actual science and actual data. Not a single thing you’ve brought up has been substantiated with scientific data.

In my city, temperatures rarely go below -20, mostly stay up to -10 in the coldest of months, but as far as salt protection goes (our road companies don’t spare on the salt as soon as there’s any snow), Lithium soap based grease seems to work fine – I also ride all year long.

I do not understanding all technical terms but in Wikipedia it is explained simply as treatment forming a protective cermet or ceramic-metal coating on the friction metal parts of the mechanisms directly during the process of their operation: https://en.wikipedia.org/wiki/Revitalizant You mention your requirement stress test of 4 ball 1000 N weld test, only to never mention of show any test data of this. As for heat, as the linked blog discussion indicates, while overall heat is usually not an issue, momentary micro heating, resulting in welding occurs regularly, and Moly might help here too, as would a high 4-Ball test due to a superior synthetic oil or Teflon film.

Bicycle hubs are not sealed. They are “sealed”. It is a valid argument. If they were really sealed, water washout attributes would be irrelevant. Bike bearings have covers that both leak and allow dirt and water intrusion. So it’s more of a “dust protection” that doesn’t seal, advertised as a seal. You have provided NO DATA AT ALL. NLGI2 is fine but is it ‘ideal’ or ‘optimal?’ No, because bicycles don’t need it. Please provide ONE study that shows NLGI2 is necessary for typical bicycle loads as thus far you haven’t provided ANY data so that would be a first. As far as I know, those are decent-quality calcium-based greases, that are softer than NLGI2 hardness, not aggressive on plastics, rubber or metal. Polytetrafluoroethylene (PTFE) was accidentally discovered in 1938 by Roy J. Plunkett while he was working in New Jersey for DuPont. As Plunkett attempted to make a new chlorofluorocarbon refrigerant, the tetrafluoroethylene gas in its pressure bottle stopped flowing before the bottle's weight had dropped to the point signaling "empty". Since Plunkett was measuring the amount of gas used by weighing the bottle, he became curious as to the source of the weight, and finally resorted to sawing the bottle apart. He found the bottle's interior coated with a waxy white material that was oddly slippery. Analysis showed that it was polymerized perfluoroethylene, with the iron from the inside of the container having acted as a catalyst at high pressure. [4] Kinetic Chemicals patented the new fluorinated plastic (analogous to the already known polyethylene) in 1941, [5] and registered the Teflon trademark in 1945. [6] [7] Minimal 4 ball weld test of 1000 N or better was a safe margin recommended by the post’s co-author, an expert on the subject, Stevan Dimitrijević. If you have relevant data that proves otherwise, please share it, I’d be more than happy to link it and correct the data in the post.”
