Finish Line Teflon Synthetic Grease

Product Information

The working temperatures of literally all the greases you listed is perfectly fine for 95% of riders out there. Trying to make recommendations by a maybe 30*F change in ambient is not based on science. These are high quality greases with excellent lubricating, water resistance, extreme pressure bearing and oxidation resistance properties.

Reason seems to be advocating for research and evidence that substantiate Relja’s views/opinions. I say the value of the post is in the explanation of grease technical specifications that allow others (like me) to make our own evaluation based on local conditions and habits. I thought Relja clearly made the point that there is no ‘optimal grease’ for every situation. Personally, Relja’s recommendations were a most welcome addition to the post.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. Basically we can conclude that you have literally zero data comparing the greases to substantiate your opinion. This is what you’ve shown thus far. Synthetic greases.With synthetic base oils. Usually have properties superior toother comparable greases. With a (significantly) higher price. The main flaw when using these greases for bicycle bearing lubrication is it’s relatively higher price. Also, low compatibility with other greases can be a potential problem – in case of adding grease without previous complete washout of the existing grease.

I’ve also explained what the minimum requirements are, how to read and compare characteristics of a particular product. Grease labeling according to standards 3.3.1. Grease consistence (hardness) labeling according to NLGI standard Why NLGI2? Why is that optimal? NLGI1 or 1.5 is perfectly fine for bicycle applications, NLGI2 is the primary grease to automotive applications. I never said lithium grease is the best. Optimal, considering both grease characteristics, as well as price, availability and compatibility with other greases – yes. In my opinion and experience. Polytetrafluoroethylene ( PTFE) is a synthetic fluoropolymer of tetrafluoroethylene and is a PFAS that has numerous applications. The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]Your argument here is the hub grease will not only leak out of the sealed hub, cross over the pawls, pass then through the freehub seals in sufficient quantity to contaminate the freehub grease to render it ineffective before environmental contaminants would require you to service the hub anyway? That’s one desperate argument and Shimano’s grease is calcium based which is compatible with calcium and poly by your own charts. It’s simply not a concern to be worried about as by the time ANY hub grease crosses that many barriers in sufficient quantity environmental contaminations would of already done much more damage. Hubs where grease temperature resistance does get put to the test are hub brake models (coaster brakes, “Shimano Roller brakes” etc.). There, the temps inside the hubs can get really high, especially if braking a lot (long descents etc.).
