|About a year ago I got a warranty replacement frame from specialized and now the seatpost creaks on every pedal stroke. It's the same size, 27.2, as the old so i'm using the same post. It's an aluminum frame. One guy at the bike shop told me to put some grease on it, but that made it slide down and only worked for a while. I'm afraid to tighten it too much and too cheap to buy a new seat post. what should i do?

|Try some anti-seize for the creak. It's not as slippery as grease and it works better for creaks in my experience. If your seatpost still slips then you'll need to turn it down a little harder. Make sure the threads and the inside of the binder bolt's head are greased. You should be able to get the binder clamp good and tight without busting anything, and if you do strip the threads (which I doubt you will unless you use a breaker bar), a new binder clamp should run you about $5.|

|Have you tried lubing the seat rails and the bolts that tighten the seat rails?
Does the creaking stop when you get out of the saddle?

|A greased post should not slip in the frame. I've been greasing seat posts for decades and NEVER had one slip down. It sounds to me like maybe it really is not 27.2.|

|I've never had a seat post that creaked. I've had saddle rails that made ungodly sounds. I just pulled off a Selle Italia Fluid saddle that started creaking like crazy while in the middle of a ride. Upon inspection when I arrived home I noticed that the composite area near the insertion of the rear rails were cracked on both sides. Try pulling off your saddle and giving it a good lookever. Then apply a light coat of lube to the post and bolts. A couple of drops of TriFlow to the bolts should do it. Remove the bolts first and wipe them off. What kind of post and saddle are you using? Your post should not slip.|

|It might not be the seatpost. There is probably a sleave that is bonded into the seattube that has gotten a loose. This is pretty common on aluminum frames. To fix it, pull the seatpost and bottom bracket and pour some boiled linseed oil into the seatube through the BB so that can get between the sleave and seattube. Allow to sit over night then re-assemble.
I fixed the same type of creak this way on a Specialized M2.

|I am also having the same problem on my new 5200 with a stock seat. I believe the noise is from the San Marco Ti-seat rails. Today I am going to lube the seat rails and bolts. I have been told not to lube the seat post inside the carbon frame due to corrosion of the OCLV frame. I hope lubing the seat rails work. If not, then I am going with my Terry Dragonfly/Easton Post combination. Later, RSG|| |
