With the advent of carbon fiber components has come the awkward change of a time-honored detail of bike building: In the past you always put a nice dollop of grease on pretty much everything when you installed components. How things have changed! Nowadays grease -- especially on a carbon seatpost -- can sometimes be a surefire path to heartbreak. The slick clearcoat on many carbon components makes it so that if they come in contact with grease they're all-but-un-tightenable. The result is that people overtorque bolts in a futile attempt to keep said components from slipping, which ultimately wreaks carnage through snapped bolts, cracked clamps, and sometimes dented or crushed components.

Inserting components dry isn't an ideal solution. Dry components make noise, they corrode, and they too sometimes slip. Tacx invented their Dynamic Assembly Compound to cure these very problems. Think of it as Oil of Olay for your expensive bike gear: Use it for anything threaded or anything carbon on your bike. Its adhesive effect on carbon/carbon interfaces (i.e. carbon seatpost/carbon frameset) will allow you to reduce the amount of tightening torque you'll need by upwards of 30%. Beyond this, not unlike using Ti Prep on a titanium frame, it prevents the seizure of carbon/carbon interfaces. It's an antidote for corrosion, noise, over-torquing, and slippage. Comes in an 80g tube.

A must have for Carbon parts

  • Familiarity: I've put it through the wringer

With pretty much every frame going carbon fiber these days, carbon fiber assembly paste is critical to installing carbon fiber components. This is actually the very same product that many manufacturers ship with their bikes for their dealers to use when assembling their bikes. Although the Tacx paste provides the necessary friction to keep things in place, it does so without the abrasive texture that is common with other brands that can wreak havoc on the finish of carbon fiber posts.

Only reason I didn't give this 5 stars is because it is assembly paste. You wouldn't give 5 stars to your daily vitamin, but doesn't mean you don't need it, does it?

Works well, no brainer

Simple and plain - smooth and pebble-free. Have tried another brand, which almost seemed to have gravel/pellets in it - bad idea.

This stuff works, you don't know it's working, but it is. Recommended for any fancy bike out there, and this tube will last you a lifetime - even when building up numerous friends bikes as well :)

how well does this work as an anti- sieze on alum. parts

I'm sure it would work, based on the consistency - definitely worth a try :)

Good Insurance

    Got the carbon paste to make the bike assembly safer. Didn't want my bike to be creaking or risk breaking a component. That would suck big time. This tube could probably last about 3 full bike assemblies. Best of all I got this for 15.99 because Realcyclist matched an online price!
