If you have carbon and other parts that like to move around you need this product.

Easy peasy greasy

As are all Park products, easy to use and this paste has a predictable amount of slip that helps you feel for the appropriate amount to apply.

Works like a charm

I wasn't having any slipping issues, but used this assembly compound on my seatpost, stem, and saddle rails after a deep cleaning. I'll keep using it since it holds things in place while tightening fasteners and seems to require less torque for the same amount of grip. Texture-wise it's very similar to Gojo. I've pulled the seatpost and saddle off a few times and haven't noticed any damage or anything. This tube will last me a lifetime, so I just wish they made it in 0.5-1 oz single-use packets.

Well, I learned the hard way. The carbon seatpost on my spare bike is fused into the aluminum frame and will not budge-tried several different solvents, etc to free it up but just decided to crank the seatbolt up & ride it--good thing that the seatpost is the right height.

I decided to get some Park assembly compound for the rest of my fleet, as a preventative measure. I removed all my seatposts and applied compound. One tube provides a lifetime supply. Problem solved.

Works GREAT!

I've used this between my aluminum frame and my carbon seatpost. Since I've changed my seatpost to a Salsa seatpost clamp (which allows mounting a bike rack, but limits how tight it can clamp the seatpost), my carbon seatpost will keep falling, even after tightening the bolt to specifications.

After using this product on it, the seatpost STAYS! It doesn't budge now. Great product! It actually works!

Very thin, doesnt grip well at all. Might be fine for some parts but not a seatpost.

I'm sorry this didn't work for you. Check out Motorex Carbon Grease, while more expensive we've received some really good feedback about it.

Tried several others, a waste of time and dollars, SAC-2 works best.

Used on carbon seat post installed in to an aluminum frame, absolutely ZERO SLIPPAGE following use of SAC-2 compound. Not the case with others I had tried previously, even when seat post clamp set to proper torque spec. Clean up easy, no greasy mess. Can't think of any cons......works well aluminum to aluminum also.

This stuff works!

I used Park Tool SAC-2 on my alloy stem to alloy handbar mating surfaces because under the force of pulling up or down on the handlebars they would slip in the stem clamp, which was tightened securely, and give a very uneasy feeling when pedaling hard -- might even result in loss of control or crash. The stem and handlebars are the correct size for each other so not a sizing problem, just a slipping problem. I applied the Park Tool SAC-2 compound on the area of the handlebar where the stem clamps around it and no more slippage no matter how hard I pull on the handlebars. Wonderful!

Super Grip it is!

I used this on a carbon stem that was creaking and it really took care of the problem. This stuff really does make the contact surface much less apt to move or slip.
