Park Tool ASC-1 Anti-Seize Compound

I purchased this thinking it had 4oz of compound and it’s mostly air inside the tube? Truly misleading. There’s actually just about 1oz of stuff inside. Update: I wrote parktool complaining about the quantity and they wrote back saying the tube didn’t fill up all the way and it’s defective. They asked me to return it to Amazon for a replacement.

Used it for a seat post and pedals yesterday, was what I expected. Wont have more feedback until it warms up and can go biking.

Have you ever seen a weight weenie who likes 21 pound full suspension mountain bikes or 11 pound road bikes, install titanium bolts into an aluminum or carbon fiber frame to save 30 grams on the overall weight of the bike? Or even worse, install a titanium bolt into a titanium frame ? (not recommended even with anti-seize compound) I have, and unfortunately I have also seen the damage done when someone tries to forcefully extract the same seized titanium nut or bolt a year later, which then has to be drilled out or in some cases can even ruin the frame. That is where anti-seize compound comes in. And Park Tools formulation is just as good if not better than any generic compound you buy at an auto store. I have no idea what the exact elements are in this Park Tools lube but I would not be surprised if it was partially Moly-50 with some zinc added for best protection with aluminum and titanium. (which also would work equally well with carbon fiber). At any rate, this lube works well. Very nice to have for bottom brackets on my titanium hardtail and for bolt hardware. I have been using this lube for multiple rebuilds over the last 15 years roughly and this has saved my butt from galled, corroded and seized components on more than one occasion. In my book, that makes it five stars!

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

Nice product, easy to apply, save me much time adjusting my bikes parts.

This stuff works GREAT! Used it to install my new Shimano Dura Ace pedals and haven’t looked back since! Compound is high quality and easy to apply from tube without making a huge mess! Buy and you’ll be glad you did! Trusted brand and trusted product!

I had to install a freewheel and thought it would be a good idea to use this anti-seize compound lube in order to keep things from getting nasty when it would eventually need to be removed for service or whatever. I use it on pedals and anything else that Ive had a problem with in the past.

Good stuff - an absolute must have for any serious do-it-yourself bike owner. But dont let the oversized tube fool you. As the description says, its 4 oz of product... but it comes in a 12 oz sized tube. A tube will still last years, but getting all the product out of it might be problematic. Great product - dumb packaging. That being said, its a great product that should be in every bike owners tool box.

Just what I expected. I like it and it works for me.

Park products are top notch for bike maintanance and repair.
