Teflon and Tri flow was not working for me. After a few rides the chain stated to make noises. A few drops of this and the noise is gone. I can focus on my riding again. The chain looks cleaner after my rides too.
ProGold Prolink is an excellent chain lube. Easy to use. Ordinarily good for several hundred dry miles if chain is kept clean between rides. May not be the lowest friction, but seems to do a good job balancing that and durability.
It's really runny. I usually use finish line dry. This was on sale so I tried it. It's really runny and sort of splashes off the chain. The lubrication is adequate but it's not magic. I'll stick with FL.
Lubricates and cleans chains making a silent drive-train. Apply immediately after a ride, let it penetrate, then wipe off excess with rags. After several applications you will be sold. Great lubricant!
Prolink is an xlt lubricant that also does a great job of keeping grease from building up on the chain. However, every bottle of it I have used in the past few years leaks when I apply it to a rag. Stop it from doing that! It is also a bit pricey.
