Hi - I'm not sure how to adjust this type of seatpost. I've been Googling around but haven't found what I need. I've figured out that the silver collar below the black dust boot can be adjusted to increase or decrease the compression of the post. Is that all there is to it? I don't understand what the hex nut with the warning label on the bottom of the post is for. Thank you!

turn it in,preload increases, turn it out, preload decreases... you want the post to not mush down every time your bum hits the seat... it should only move when you hit a bump without lifting your bum.

the collar holds the post together, and can also lend a bit of damping to the springy action, lessening "bounce"...

on a personal note.. i hate those heavy spring posts.... and thick gel seats make me feel like i filled a diaper... NOT something i want to feel when riding a bike. Riding more often, correctly setting seat height, and learning to keep more weight on the pedals does far more to lessen rear end pain.... and setting the handlebars too high only INCREASES the pains, lower back included.

Thanks! That is helpful -- use the hex screw on the bottom of the post to do most of the work and adjust the collar to fine tune. Also, appreciate the other tips!

Do most of what work? I don't see any other hex screws that affect how the post moves, just the standard bolts for adjusting height and level that all posts use.

Let me take another stab at this -- in order from the bottom of the first photo, there is the clamp that tightens the seat post so it doesn't move up and down; then there is what I am calling a collar, which is threaded, and does influence the degree of compression; then there is the black rubber boot; above the boot you can see what I think is a component of the suspension (a shaft with channels). In the second photo there is the pretension adjustment on the bottom of the seatpost. What I am trying to get at is the difference between the functions of the pretension screw on the bottom of the seatpost and the "threaded collar." Do you set the pretension first and then make fine tune adjustments using the collar? That's about the best I can do to explain it. Pretty sure I'm over complicating this a ton!

Simply things and ditch this thing which wasn't made to last and not really great for adjustment and get yourself a Kinekt seat post and you will be much happier. These pogo stick styles of seat posts are a cheap way to make it seem comfortable but in the end your knees just go up and down which is not ideal for them ultimately it changes the position on your bike and is not a good reliable companion. We call them captains chairs because eventually they start to swivel completely but at the moment will likely have play which get worse and worse.

The Kinekt is designed to go down but also backwards and has two springs that can be swapped to suit your riding or weight and has an easily adjustable preload bolt. It really takes the edge off of big bumps and makes small stuff just disappear. Yes it does cost money but in the end should last for a long time and with the replaceable springs it is a more durable option than say the Cane Creek Thudbuster (which is the one Cane Creek product I am not a fan of) which uses rubber elastomers and in the end won't or should ever twist and if it does take it back to the dealer and have them reach out to Cirrus Cycles or reach out on your own and they will probably help out they are a good company.

I personally have two of these posts and was not for them until my boss (R.I.P.) got one and said go test it and in that short ride I was sold. I remember when they were just a kickstarter thing and I was like "no ugly heavy not convinced" but their newer version at the time I rode it was much sleeker and the comfort was the easy sell I hit potholes like I had it in for them and didn't really notice them which was awesome.
