How do I tighten my spring-loaded seatpost?

[Guest]

I have a bike seat post that is spring loaded. It's come loose the last week and I'm having a hell of time tightening back into place. Is there a trick to this?
Thanks, Chris

Hi Chris,
I think if you take your seat post out of the frame and look up inside it you'll see an allen bolt... you'll need a long key for this.

Thanks Alex! I'll give it shot!
