    Perfect for use on cleats to prevent bolts from falling out.

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

    Awesome Compound, it really does work. I will say its a lot for the price but since its made in America you get what you pay for. It will last me a long time, as long as you use it in small amounts, it wasn’t just perfect for my bottom bracket, but Threaded surfaces like limit screws, axles, cone nuts, axle nuts, threaded spacers, etc. Ive used this on Limit screws, my Bottom Bracket, any place with a machined threaded surface, hole etc. In fact on my bottom bracket shell of my frame was threaded, I did put ASC-1 grease on the threads inside the shell before installing the Bottom Bracket. The biggest problem I have had is the stripping of the threads, which is my biggest problem, so I started using it on screws on my derailleurs including my freewheel, and anything and everything with a threaded surface going into metal parts. This stuff really is awesome, and Park Tool is a brand and company I trust completely they really do know what theyre doing. My only Recommendation to Park Tool is to put this in a tub like they have with PPL-1. Otherwise if you go through a lot of this you have to be prepared to spend a lot. Otherwise, I highly recommend it!

    I purchased this product to use on new Shimano SPD-SL pedals I was putting on my road bike. Got the idea from the Park Tool YouTube video on how to change bike pedals. Only advice I can offer is to use it sparingly. I thought I was being stingy with the amount I put on the threads and noticed that upon tightening the excess grease ended up all over my pedal cranks. Trying to clean it up is very hard and messy so apply as little as possible to get the job done.

    Used this to lightly grease my freehub (to help prevent corrosion) and cassette lock ring. It also does not have a strong odor.

    You apply this on joints and threads that are not meant to move against each other, so that you can take them apart in the future. If youre like me, and was clueless about whats the difference between anti seize compound and polylube, watch the video by Park Tools showing the difference. If youre packing ball bearings, use polylube, not anti seize compound. However, you can use polylube to grease threads. So why get anti seize? They are supposed to last longer, and also prevent galvanic corrosion between dissimilar materials. May not matter much with bicycles, especially for parts that get removed and grease reapplied regularly. But I had a tough time removing my old pedals, and decided to get this as it doesnt cost much and I expect to need it somewhat frequently.

    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.
