Hey there!! I'm 285 and going down, used to be 350 last summer.
I can't seem to keep my post where I want it. It will gradually slide down as i ride. The small bumps, and my weight of course, make it go down bit by bit. I'm sure I have the correct post size for my bike. Any tips or tricks on how to safely secure the seatpost and prevent it from slowly sliding down?????

Are you using a QR seat collar?.....

In my experience with and being a heavier rider that many QR's just don't provide enough torque to keep the seat post in place. My suggestion would be to replace the QR with a bolt tightened type collar. My favorite is a Salsa lip lock. They are very strong and put allot of torque on the tube and keep things in place quite well. Depending on how long this has been happening you may need to replace your seat post as well. The post sliding down into the seat tube with the collar cranked down will cold work the post and actually make it smaller in diameter over time. You may not be able to torque the collar down enough to keep it in place after a while.

Anyway, I would recommend getting a Salsa Lip Lock in the proper size and installing it. If the seat post continues to slip then replace the seat post as well. If you really want to stay with a QR type collar then the Salsa Flip Lock is probably one of the best on the market.

Put a hose clamp around the seat post butting up to the top of the frame seat tube to keep it from slipping. Don't look that cool, but it works.

Try a Thomson seat post. I've had the same problem on three different bikes...fixed it each time with a Thomson seat post.

If you go to a shop- feel one - they have "rings" from the machining process that give some grip that help the post stay up.
