Regular grease reduces friction between surfaces, which is the opposite of what you want at a clamping interface. A greased seatpost or stem is more likely to slip under load, tempting you to overtighten the bolts, which can crack a carbon part or strip threads on an alloy one. Assembly paste, by contrast, contains fine grit particles that increase grip, letting the same clamp hold securely at correct, safe torque values.

Clean the contact surfaces of both parts to remove old grease or paste residue, then apply a thin, even layer to both the inserted part, such as the seatpost, and the inside of the clamp before assembling. Tighten the clamp bolts to the torque value specified by your bike, stem or seatpost manufacturer, since the paste is designed to work at the recommended torque, not to replace it.

Yes, this type of assembly paste is formulated for use on carbon-to-carbon, carbon-to-metal, and metal-to-metal clamping interfaces alike, including alloy seatposts, stems and handlebar clamps. It is a good default choice whenever a manufacturer specifies a friction or carbon paste rather than grease at an assembly point.

Since only a thin film is needed per application, a 500g bottle typically lasts through many seatpost, stem and handlebar installs or services, making it a practical size for a home workshop or a small bike shop. Keep the lid tightly closed between uses to prevent it from drying out.
