Many people have been having trouble with carbon seat posts slipping. I have seen all kinds of solutions which I always say, "It may work for a bit, but that is not designed to do that." So, there is a right way, and then there are other ways. The other ways people seem to think work range from loads of tape, cleaning off the post and cleaning out the frame so it's bone dry, and then also using traditional grease. Those ways are not recommended. Instead, use a carbon specific grease and tighten your bolts to recommended torque specifications. Here is a step by step method that Morgan, from
Fitness Fanatics, demonstrates.
Finishline Fiber Grip
Get a portion of it on your finger...
and rub it up and down the post...about 3-4" from the bottom.
Insert the post back into the frame...
Torque to appropriate load. Most seatpost require anywhere from 4 to 6 Nm, and they normally say what the Nm they require on the seatpost cuff.
If you don't have a torque wrench, and you have a bike with many carbon parts, I strongly suggest you invest in this tool. Frame manufacturers are not warrantying bikes that are cracked because of owners over tightening bolts. And one of the most common bolt that is over tightened is the seat post because people use the wrong grease. Horrible cycle.
