Thanks for the follow up. It sounds like the post has deformed. Check into an interesting product we are playing with and have had some great feedback, so far:
Syntace friction paste. It has a higher coefficient of friction, prevents corrosion (the intent of lube here), and actually lowers the amount of torque (approx 30%) needed to hold a post in place; hence may reduce deformation especially on light weight carbon and alloy posts.

DYNAMIC Assembly Paste
As a trend-setting innovation in the bicycle market, the new assembly paste from DYNAMIC is indispensable whenever high quality carbon and aluminum components have to be assembled.
This paste has a strong lagging effect without any tendency to gum up or stick. This permits the tightening torque at the clamping point to be reduced by up to 30%, so there is no longer any danger for the clamping bolts being overturned. Ensuring undiminished locking properties, the paste relieves stress on sensitive carbon surfaces, prevents damage to the fibers and eliminates cracking.
The assembly paste ensures maximum protection against corrosion and is highly resistant to spray. It can be used for all carbon, aluminum and steel connections requiring 100 per cent reliable locking and protection against corrosion.
- Seatpost
- stem, handlebar
- Inside bearing bushes, pedals, cranks
- Screw threads
- Water resistance: high
- Viscosity: very high (at 20°C)
- Coefficient of friction: very high
Order numbers: F-023 for 80 gr. tin / F-023B for 400 gr. tin
Please find hereinafter a detailed description of the main properties of the assembly paste:
CHARACTERISTICS:
The paste is designed as a highly resistant parting compound and not primarily to be used as a conventional lubricant.
Highly resistant to mechanical load, the product can be used as a 100 per cent reliable parting agent. As there is no contact between the friction surfaces, there is no danger of two pieces of metal “welding together” or c
ceramic and plastic surfaces suffering from material breaking out.
At temperatures from – 50°C to + 150° C the product shows a constantly high coefficient of friction ( ˜ 0,1 μ ) which effectively prevents assembled parts from loosening.
The paste is neutral to copper and aluminum alloys, steel and synthetic material.
RANGE OF APPLICATION:
Assembly of bolted or clamp connections which are exposed to high mechanical load, but should not loosen or move.
Assembly of threaded pins exposed to high load which cannot be locked by a screw fastener, but should not seize solid and should be easy to release even after prolonged use (at temperatures up to approx. + 600°C [dry lubrication]).
USE:
Prior to applying the paste remove dirt particles (dust etc.) and lubricant residues from the surfaces to be treated.
Then apply a thin and even coat of DYNAMIC assembly plate to the cleaned surfaces using a brush or a lint-free textile or leather cloth.
Close tin after use. Storage life: 10 years if stored in accordance with instructions.
Stir paste before use!
