During long rides my seat post would slide down very very slowly. By the end of the ride my seat was too low and causing knee pain. The slipping seat post and knee pain wasn’t obvious at first. I finally used this product and my seat post does not slide down at all anymore and knee pain has been significantly reduced. Review: Great stuff! - I recently purchased the Park Tool SAC-2 Assembly Compound to use on my bike's carbon seatpost and handlebars, and it worked exactly as advertised. Application was easy — just a small amount provided a noticeable increase in grip, and I didn’t have to overtighten anything to keep it secure. It gave me a lot more confidence, especially knowing how sensitive carbon components can be to over-torquing. The texture of the compound is a little gritty because of the silica, but that’s what helps create the extra friction. I was careful to wipe away any excess to avoid cosmetic blemishes, as the instructions recommended. Also, I made sure not to use it on any threaded parts or bearings, since it’s not designed for that. Overall, I’m really happy with the SAC-2. It’s a simple product that makes a big difference in keeping everything tight and protected. Definitely a great buy if you're working with carbon or aluminum parts! ## Features - Creates a tighter grip between surfaces, reducing the amount of clamping force needed to safely secure a component - Ideal for carbon or lightweight alloy handlebars, stems and seat posts - With more and more manufacturers specifying that assembly compound be used when assembling their components, make sure that you are not invalidating your warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005Z4BAAK | | Best Sellers Rank | #10,246 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #21 in Bike Lube | | Brand | Park Tool | | Brand Name | Park Tool | | Container Type | Pail | | Customer Reviews | 4.8 out of 5 stars 2,109 Reviews | | Global Trade Identification Number | 00763477006141 | | Included Components | Assembly Compound | | Item Form | Liquid | | Item Weight | 0.25 Pounds | | Manufacturer | Park Tool | | Material | Alloy Steel | | Package Information | Pail | | Recommended Uses For Product | Bike | | Specific Uses For Product | Assembly Compound | | UPC | 763477006141 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Park Tool - **Item Weight:** 4 ounces - **Material:** Alloy Steel - **Package Information:** Pail - **Recommended Uses For Product:** Bike ## Images ![SAC-2 Lube Assembly Compound (4-Ounce) - Image 1](https://m.media-amazon.com/images/I/81iQwxuYf7L.jpg) ## Questions & Answers **Q: I misinterpreted what they meant by "sac-2" and thought i was buying chamois cream! help! what do i do!?** A: Do not use this in place of the chamois cream. I used it to keep my carbon seat post from moving. It may work for other things too but I'm sure it would not be a good replacement for chamois cream! Lol **Q: Will this work for regular steel (chrome) on steel seatposts?** A: What for? The reason we put this on carbon is carbon might break, when ur using steel...... Get it? **Q: Bought a new stem (eastonea70) and even when tightened all the way the handle bars still roll forward with pressure. will this work w non-carbon parts** A: I'm sure this will work with non carbon parts as it is just some grit in grease (oversimplifying) but you may have more of a sizing problem with incompatible parts **Q: I need a little more grip for my computer mount on my carbon bars without tightening the mount further. Will this work?** A: That might work. Keep in mind this compound is made of particles that feels like a very thin sand and it might ruin your carbon finish over time. If the intention is just preventing your computer mount of moving I would try a double-sided tape instead. ## Customer Reviews ### ⭐⭐⭐⭐⭐ My knees say thank you! *by H***G on January 31, 2026* This saved my knees.
