Assembly compound to prevent slippage between two surfaces. Perfect for extra grip for carbon, aluminum and steel seatposts, handlebars and stems.
Note: Not for threaded surfaces. Do not use for bearing lubrication.

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.
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!
Absolutely the clear ticket for keeping my carbon seat post in place in a carbon frame. Great for keeping any other carbon parts lubricated from slipping with minimum torque.
I was having trouble with my aluminum seat-post slipping in my ti bike. This stuff solved the problembut be careful how you use it. At first I thought it was like a lube so spread a thin layer on the length of the seatpost, which was a mistake... I was barely able to move the post once it slid in just an inch or so. Next I used grease on the post and just put a thin 12 wide strip of this super-grip up near where I had marked the insert depth on my post. Now the seatpost never slips down during a ride.
Very thin, doesnt grip well at all. Might be fine for some parts but not a seatpost.
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.
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!
