Park Tool SAC-2 Lube Assembly Compound (4-Ounce)

Works good but you still have to tighten your nuts down a good amount. Made in U.S.A.

I'm about 240lb and 6'4" so lots of pressure, leverage, etc where last 4 bikes regardless of clamp, double clamp, tightness, post, dry, etc seatpost would slip. I have aluminum to aluminum, not c-fibre.. the competitor product that is marketed to carbon for anti slip did not work at all, made it worse. The only thing that worked was cleaning it and adding climbers chalk, as weird as that sounds, but with the chalk I'd have to reapply, and it would creak a bit.So I tried this park product and it actually worked. No slip, no creak. Finally.. very happy with this. Don't hesitate to purchase this.

Easy to use; solved my bike seat issue. Great product!

Seat was slipping on bike, applied to post hasn't slipped yet. Very satisfied.

I believed I needed this Supergrip Assembly Compound with a dropper seat post. I had to use an adapter between the aluminum frame and seat post. Manufacturers of dropper seat posts caution the user about proper torque for the seat post clamp. Since there are internal parts that move vertically, over-torqueing could interfere with post movement or damage the dropper outer tube. The compound increases grip without the need for excess torque.In addition, deburring the ID of the seat post tube is important for proper grip. I have a mountain bike that had an interference-fit 1/2 down the tube. The welds for a brace had distorted the seat post tube. An adjustable reamer was required to remove 0.15mm of aluminum. The moral is to ensure parts fit without undesirable influence.I do not believe a normal installation between two parts would require this compound. I’m installing a dropper post that fits the seat post tube. I will not use this compound because proper torque – measured with a torque wrench – will clamp without slipping. In addition, the compound does damage finishes. Some excess torque on a standard seat post would be fine. Just determine the weakest link (clamp, bolt, post) and do not exceed the recommended force. One more thought: torque can be applied to dry or wet threads. If lubrication is applied to threads, then derating the torque value is necessary. Dry Torque x 0.6 = Lubricated Torque (>/= 30W oil, anti-seize, grease).The SUPERGRIP™ compound comes in a toothpaste tube that is an identical size, cap, and colors to Park Tool: ANTI-SEIZE COMPOUND, POLYLUBE 1000™. The only difference in these tubes is the heat-seal end of the tube is a different color. I used green painters’ tape to identify this compound with a noun & caution. If somebody other than me uses these tubes then they hopefully see read the label and see the caution.

Using a tiny bit helped me get the appropriate torque on a steam bolt, fixing a potentially deadly twisting issue.

What can I say???? Park Tools stuff always work great.

Held bike stem in place quite well.
