So today while it is raining out and no riding for me today I decided to take my suspension seat post apart and see how well it was greased and to see what was inside it. First I took my 8mm hex and backed out the bottom screw. You can easily back it out as it won't fly off at all as the spring is short enough to not put pressure on it. Once the screw is out of the end there is a plastic spacer that is taper at the end that goes into the spring. After the spacer is the main spring and that's everything in the bottom. I checked it all out and everything was greased up well. Put the spring back in, the plastic spacer and then the put the 8mm nut back on. For my weight it's screwed in (.293") on my digital calibers or a little over 1/4" in and it's ready to go. You may need it in more or less depending on your weight.
