Fitting carbon seat post to carbon frame

Question : Grease / No Grease ????

Fits in snug without but its just I heard arguments for both Yes and No..

Thoughts please .. As always , Appreciated

Carbon assembly compound.

As I understand it the objective is to stickify, not to lubricate.

Is this a must do or do you reckon its ok to fit without this compound ?

Carbon assembly compound is a good idea; it will hold firm at a lower torque.

I've not had a problem using nothing either.

Buy a tube of the Tacx stuff, it's cheap and it will put your mind at ease:

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.

touch of cement will do you fine. If you really want to be sure that the seat wont move, take it out, pour the cement into the seat tube and see how far in the seat post goes. Keep filling until your desire ride height is achived and allow cement to harden.

NOTE: this may add a slight bit of weight to the bike.

What also works instead of compound is..... hairspray. Seriously. Thats what I sprayed on the aero seatposts of my Cervelo S1 and Planet X Stealths. Stopped them slipping just as well as the compound did.

Tomorrow, I will demonstrate how to make Mavic Cosmics out of Cereal boxes and insulating tape.

I've heard the hairspray recommendation from mountain bikers to secure grips. If you don't have any already though carbon compound is probably as cheap It works well to stop handlebar/stem creaking too; despite the name it works as well on alloy as carbon.

@Bikerbhoy- worth considering a torque wrench when clamping carbon components. Ritchey do a very handy small one which uses a 4mm hex pre set to 5Nm. This does virtually all my stems, bars and seatposts.

ALL SORTED.... Carbon Compound it is from the boys at Thinkbike.ie , seatpost fitted and ready to go,

Thanks for your comments lads........ Hairspray.... JEZ what wud the mot say now if see seen me lightly dousting my components with her best Wella products actually doesnt bear thinking about....... Fair play Quigs Im sure it works...LOL
