The Antishock QL suspension post is designed to smooth vibration and take the edge off of larger hits to help reduce fatigue and extend your ride time. Perfect for the gravel racer or touring cyclist looking to relieve their lower back over the rough sections or the hardtail rider that wants to calm those unseen rocks and roots.
The four-link suspension has 20mm of travel, and maintains your saddle angle throughout the movement for a more natural pedaling feel. The Antishock QL ships with three interchangeable elastomer blocks to easily tune the suspension for rider weight and individual riding style.

2. Push lower pivot pin out completely and slide linkage open.
3. Remove elastomer. 4. Replace elastomer with concave recess on top where it fits around the seat clamp assembly. 5. Close linkage around elastomer aligning lower pivot holes. 6. Grease and reinstall lower pivot pin. 7. Insert screw pin at front of post and tighten to 2 N/m

Good comfort for the cost if you don't mind a little weight. Only negative is on really steep downhills the seat rises up to full height cause you aren't sitting down on it, which feels sketchy. With the roads getting rougher this helps if you can't fit big tires on your road bike. I max out at 28's.I was able to use the extra elastomers to help dampen and strengthen a drop thru rigid Mtb frame I designed.

I figured others were just not installing correctly, but I tried many attempts to get it to work and it always ended up slipping while ridding. I wish it didn’t because I think it was nice for the few minutes it held tight.

After doing tons of research. This was the one I chose based on the reviews. The price was with within my budget. It's definitely not as good as redshift, but it's also not nearly as expensive. I can't complain so far, I use it on my street bike and not my off-road one. Do I wish I bought the redshift yes! But at a fraction of the cost I don't see anyone going wrong with this.

Very smooth for my lower back, no more shocks. It’s fantastic, I’m very happy of my purchase.

I was originally ambivalent about the quality and feel of any suspension seatpost as I was originally a hammerhead racer and was concerned about the loss of energy climbing or grinding in the saddle. Some reviewers also left me with doubts. I left it with the stiffest elastomer and noticed it really took the edge off small bumps in commutes. There was a teeny tiny bit of looseness 'yawing' atop the seatpost that others complain about but it almost to me, felt like an improvement. The true test was riding on the magnificent C & O Trail with the same tires I use on tours (Old, stiff Panaracers 700 x 38 Tourguards) and it passed with flying colours. It's compliance and comfort on gravel, roots and rocks made long distance ergonomics much more pleasant and less exhausting.

One horizontal bolt to hold the saddle is the worst system known in cycling. And I know it, and I'm paying the consequences. The headaches of having your saddle out of angle doesn't worth this very short close to none travel seatpost. It's heavy and don't do the work not even riding on sidewalks. Look somewhere else.

I weigh 205 lbs and put in the appropriate elastomer. Have put about 100 off road miles on my cyclocross bike and I'm pretty certain it hasn't flexed one bit. I'm going to switch to a lighter elastomer and see if that is better for my weight. This is my second one. First one returned do to inability to reinstall pin after elastomer change. This one was no problem. I love the build and design.

This antivibration seatpost is awesome, which meets my expectations (price, performance, and look). No more sore bottom and most importantly sore back after long rides.I am a 6-foot, just below 200lb-ish guy (daily riding is helping me to get toned), and didn't have any experience about a hard tail bike, Scott Sportster (my primary bike is Jamis XC Dakar, kind of full suspension MTB, which was at the repair shop). In urban paved roads, its condition is pretty harsh - pot holes, debris, gravel, nasty road kills, etc). All vibrations and bumps are directly hitting my bottom and back, casuing soreness and pain - I didn't experience these while riding my MTB, relatively speaking. I was looking a moderate/affordable suspension seatpost so that I could ride Scott Sportster comfortably until my Jamis is back.Price: under $80 is very attractive, compared to industry leading (very serious) seatpost products at $180 plus.Performance: I installed the hard elastomer (#9) because I would like to just dampen road vibrations only (and I am over 190 lbs threshold). Medium elastomer (#7) gave me very comfortable ride (fully bouncy), but I didn't like that feeling - very weird when you pedal hard... Now I could attack harsh urban paved roads without any fear nor hesitation!! All those vibrations have been minimized (not fully disappeared) so that you could ride long without any soreness (10 miles a day during the week, 30+ miles during weekend: about 100 miles a week). This performance was exactly what I expected. If you expect more bouncy feeling, you could use softer elastomer or look for other suspension seatpost with higher movement (more than 20mm).Installation: it was pretty straightforward. Single bolt saddle mount is convenient. However, I had a hard time to swap my WTB speed saddle to this - very tight saddle rail clearance. Eventually, I made it and my saddle was locked in (didn't apply a fiber grip, but it was secured). Back of the seatpost has a ruler so that you could easily adjust its height, no need to use your finger, or screw driver as a measuring tool.Overall, I love this seatpost much, very easy/affordable way to upgrade your hard tail bike!!! Highly recommended!!!

I'm 150 lbs, kinda between the softest cushion setting and the middle weight cushion. I went with the softest ride (100-140lbs Rider). It works ok at absorbing shock from rough gravel roads. It's not very noticable. Not sure it's really needed but it does smooth out the ride a tiny bit on gravel roads or bumpy terrain. On smooth road probably not needed. I didn't notice much bobbing up and down during pedaling. The weight vs benefit of a smoother ride is acceptable. Overall more of a "nice to have" but not essential upgrade. I haven't tried other posts, I chose this for weight, travel, and price.
