Great Low Cost Suspension Seatpost
Product came promptly and in perfect condition. The adapter fit my bike perfectly. The adjustability feature really didn't make much difference in performance. The seatpost is firm but does absorb harsh bumps. The five stars does not imply that this product is as good or better than similar items costing much more, only that it's worth every penny that I paid, is solidly made, and is a definite improvement in performance over a stock hardtail bike. If you ever ride over bumps (and who doesn't) you will appreciate having this suspension seatpost.

I love these ride smoothers! Great price!
I recently purchased 6 use bikes over a 7 month span for my entire family. I purchased one of these and added it to the first bike. I was so satisfied that I purchased 4 more of these Zoom seatpost. It really makes your ride more enjoyable, less shock on your spine over the bumps and these are a great price, adjustable, and well constructed. They do exactly what they are supposed to do!

Good product
I like the product okay. Wished it was a little better rebounding. Works good even with the slow reaction.

Helps make bike comfortable on bumps
This (and a suspension front fork) make my new e-bike comfortable on bumpy streets, very common around here. Fairly easy to install.

Decent budget suspension seat post
This is a decent suspension seat post. It is enough to absorb sudden impacts and prevents hurting your bottom. Do not expect a cushy ride, this is not designed to be bouncy. It still rides stiff. Build quality and material is good. I was able to adjust the stiffness easily. My one issue with this seat post is that it forces me to ride higher due to the suspension travel and there is not a way to lower it. Due to the size of my bike, my previous setup, i have the seat post at its lowest setting. This is just about right for my riding style. However, with this suspension post with the added suspension travel, it forces my seat to be 3-4 inches higher when installed at the lowest possible position on my bike. My riding position is not the best and my legs are stretched when the pedal is at its lowest. Just keep this in mind.

Great price, quick installation, works as expected
I have the new T42 ebike that came with 33.9mm seatpost and this one was able to replace that with no issues. I'm 5'10", weigh 160lbs, and the suspension does provide adequate travel that takes the edge off when going over bumps. I'd also replaced the stock seat with a Cloud9 so with these two products, I feel like the ride is much smoother. Surprisingly, this seatpost also fixed the angle of the saddle which was pointing way too low, even at the highest setting that was causing me to keep slipping forward and having to constantly readjust. The saddle is now sitting at the correct angle which solved 2 problems for me. For the price, it's well worth it, I highly recommend it!

Good improvement for bikes without suspension
Second time I purchased this from this buyer. Solid improvement over a standard post. Well-made in fairly priced.

Saved my A**!
Oh glorious relief. My old a** was getting roughed up. This seat post replacement is amazing. Very easy to install and for me, came at the perfect setting. I didn't have to adjust the dampening at all. It does make a slight noise when it compresses. It kind of sounds like a zipper on a tent being closed quickly. A little dry? Don't know, don't care. Every time I hear it, I think "that could have been my back side. It's working!" I just added the underseat bag recently for tire repair goodies. It works with that on there as well. So stoked it all came together and works so well. Great product, and for the price. Wow!
