DJC Bike Suspension Seatpost Shock Absorber Damper Post 27.2 30.9 31.6 mm, Lightweight Aluminum Body

No real instructions, but the process is pretty straightforward. The bottom line, this item works flawlessly. Make sure you know your seat post diameter when you order and that's the key. Adjustment of the cushioning is trial and error, but I just happened to get it right the first time. This is not a $200 item so the setup process is probably not on par with those. I weigh approx. 160 lbs and it's smoothed out my rides probably tenfold. No more jarring rides as the seatpost absorbs well. One of the best purchases I've made this year.

I installed the DJC Bike Suspension Shock Absorber on my bike and it made a noticeable difference in ride comfort, especially on rough pavement and small bumps. The suspension really helps absorb vibrations that normally travel straight through the frame and into the seat. Installation was simple and the build quality feels solid. The aluminum body is lightweight but sturdy, and once it’s installed you can definitely feel the suspension working when riding over uneven surfaces. If you ride an e-bike or do longer rides, this type of seatpost upgrade makes a big difference in reducing fatigue. One thing I realized after installing it is that the seatpost improves comfort a lot, but it works even better when paired with a wider, more supportive saddle. I ended up using the BLUEWIND Bike Seat, this model https://amzn.to/4cDv6cN and the combination of the suspension post plus the oversized saddle makes rides significantly more comfortable. The suspension absorbs the bumps while the wider saddle distributes pressure better, so together they create a much smoother ride — especially on longer trips. Overall, the seatpost alone is a great upgrade, but pairing it with a comfortable saddle really completes the setup and makes the bike feel much more enjoyable to ride. 🚴‍♂️

This is a nice suspension post for a reasonable price. I got the gold and it looks pretty cool on my bike. I got to say a Suntour post is much better but more expensive also. the problem I had was my thick seat made it too tall for me so I though I would give this a try. This suspension bike tube work great with my thick seat and I can adjust it accordingly to fit my height. It has great cushion for this nasty bumps and you can make it firm or soft however you choose. So it a great option for a 3rd of the price. The only real problem I have with it is the adjustment for raising and lowering the front and back of the seat is kinda lacking a bit. It could use a couple more slots to be able to adjust it a little more. Thats pretty much the limitations of it for myself. If you need some cushioning for your bike and you’re on a budget this post is definitely for you. A good option at a reasonable price. Thanks Don

Great price, shipped & delivered fast

Works. Very good for mtb.

Title: Great Shock Absorber, But Defective Pin Makes the Seat Unstable I bought this seatpost thinking it was one of the better, top-tier ones that Amazon sells — and in many ways, it really is. The shock absorber part of this seatpost works fantastic. Honestly, that part is superior. It compresses and rebounds just like it should. You can feel the difference right away when you ride. It really smooths out the bumps and gives you a much more comfortable experience, especially if you're like me and spend a lot of time riding around town or doing deliveries. So I want to give credit where it’s due — that part is excellent. But here’s the problem: the part that holds the seat itself — where the clamp bolts onto the seatpost — has a major flaw. There’s a little pin in the back that’s supposed to hold that section firmly in place. That pin is either defective or not designed properly, because it doesn't keep the seat locked down the way it should. The result? The seat twists and rotates even when everything is tightened down. It doesn’t stay solid. You try to ride with a seat that wiggles and turns on you — that’s not safe, and it’s definitely not comfortable. So yes, the suspension part is working beautifully, but that doesn't help much when the seat itself feels like it might spin off underneath you. It defeats the whole purpose of the design. I’m not trying to bash the product completely. Like I said, the engineering of the shock system is really impressive — one of the best I’ve experienced on a budget seatpost like this. But it’s frustrating when one small part — one tiny pin — ruins the whole function of the seat clamp. That pin is crucial, and if it doesn’t hold, the seatpost can’t be trusted to do its job. I’m not sure if I just got a defective one or if this is a flaw in the overall design. Either way, it needs to be addressed. I’d be willing to try a replacement to see if it was just a one-off issue, but if this is consistent across other units, then I can’t really recommend it until they fix that. As of now, I don’t have a good opinion of this seatpost because of that flaw. It’s not about bashing the company or the product — I just want something that works, especially when I rely on my bike every day. This product has a lot of potential. It’s 90% there. But that last 10% — the part that actually keeps the seat firmly in place — is too important to overlook. So here's hoping the company takes this feedback seriously and either sends me a replacement that’s fully functional or improves that seat clamp design going forward. Thanks for reading. —Rich

I'm 6'4 / 230lbs and do recreational riding for health and fitness. I purchased this DJC Suspension Seat Post for a new bike and found it to be every bit as good as other models I've owned that were three times the price. For my style of riding i.e., paved road and smooth dirt trails, it has performed as well as the others and I'm happy with it. Installation is easy if you understand how to turn a wrench. Make sure you measure your seat receiver tube correctly prior to ordering.

Bought this to replace the dropper seat post on my Ride1Up Trailrush. Improves the Ride a lot when riding over small bumps. 31.6 fits perfectly.

Riding on uneven pavements and gravel paths, it removes most of the jolts on my bottoms so the ride becomes at least 80% more comfortable than not having it. The device is inexpensive and simple to install, so I can give it a 5 star rating.

Magnifico producto e invento, peso 72 kg y ajustado el resorte en lo más blando, me mantengo como en el aire, todo el tiempo está trabajando el resorte, no contamina el pedaleo en lo más mínimo, sin embargo absorbe sorprendentemente las imperfecciones, también es cierto que el asiento de mi bicicleta es de los pequeños como de carreras y me molestaba bastante al cabo de 10 min de usarlo por eso decidí comprar la suspencion, pero en realidad esta no me quito la incomodidad, cambie el asiento por otro más cómodo y la combinación de los dos fue la combinación ganadora, el solo asiento hubiera quitado las incomodidades pero con la suspencion ahora si parece que el cuadro trae suspencion atrás. Ahora puedo andar todo el tiempo que quiera y no me molesta para nada, el peso es obviamente mayor que la tija sin suspensión, pero vale el peso extra el cual no tengo el dato pero me parece que es muy liviano considerando que trae resorte y mecanismo interno. Además el precio es muy aceptable.

مريح جدا في الاستخدام الاولي وامتصاص الصدامات ممتاز

Works as advertised. You get better results if used in combination with a soft or comfortable saddle, or a saddle that has its own springs. Pre-loading was easy to use and this suspension post does smooth out the ride a little but might require tweaking for your own personal preferences. Unsure how it compares to something like the Suntour NCX style suspension posts. Probably not as good, but this is less than half the price too. Definitely makes the ride less hard on your rear end and on your back.

Fits perfectly and works well
