    Works as advertised. Important to grease the connection between the pedal and your crank.

    Used for pretty much any metal on metal on my bike rebuild. When I have to change or remove anything the screws come out like butter I highly recommend this product for any bolt you are concerned you may need to remove later on.

    Worked great for putting on new pedals and also putting cleats on my shoes - a little goes a long way.

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

    This is pretty good stuff. I always keep this, or a can of Titanium Grease in my trunk. I gave this four stars because it is very industrial, and it can be pretty messy when used on anything in the house. Great stuff though!
