    You could probably find it cheaper in an automotive store, but I like the assurance from park tool that it is good for bikes. The tube is a much more convenient applicator than a brush and jar.

    Its been a couple months so I have no idea if its working - 5 stars! (I trust it is. This review will quickly change to 1 star if something seizes, though.)

    It works great. Pretty nasty stuff so use just a little or you will be cleaning extra grease for a while.

    This stuff works great. Its particles increase friction, and your torque levels significantly decrease because of it so you dont over-tighten your bolts. I probably use this more than my standard green grease, but it this has its specific uses and blue is my favorite color so I’m biased. If you have high quality aluminum, titanium, or carbon components, this compound is fantastic. Highly recommend having this in your tool box, junk drawer, bicycle fanny pack (you do you). This is for sure an essential item now that I have bought it and determined it as such.
