|I posted this in the general section but no responses. so I thought I would toss it in here to see if anyone here has some advice. Hey all, just got my new bike rolling this weekend. So far so good, but I am having a small problem with the seatpost slipping. I set the post to the height i want and then within a 1/4 mile it drops about 1/8" so far no more. I have a 2000 Schwinn Paramount with fastback seatpost clamp. The size of the seatpost is right. I have cranked the bolt as tight as I dare for fear of stripping. Any ideas how to fix this.

|I went through the same dilemma a few months ago and learned a few tricks. First, make sure the post is sized correctly, if it's new, check to make sure it's not undersized. Same goes for the seat tube.
Second, if it's a carbon post, don't grease it.
Finally, and this is where I solved my problem. Grease the heck out of the seatclamp bolt. If it's dry, you can't torque it down correctly. If it's a ti bolt, toss it. They stretch and will eventually snap.
You can also rough up the inside of the seat tube with some 100 grit paper. But I bet if you try all of the above, the post will hold.

|1. Clean the seatpost well with cloth.
2. Grease the bottom 2 cm.
3. Clean the frame and insert the post. Crank it.
4. Spray some WD-40 (or similar) between post and frame (do not overspray) to eliminate creaking sounds.
That is all.
