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

I have an electric trike ebike with no rear suspension and I go out and ride this a lot this makes it feel like it has a full suspension matter of fact I even just bought another one for my other e-bike get this over what you would think is a good seat cuz even with a bad seat this works really good

Huge comfort upgrade for the price — makes rough rides noticeably smoother I added this suspension seatpost to one of my bikes, and it’s one of those upgrades you feel immediately. If you ride on rough pavement, sidewalks, or even light trails, the difference is pretty noticeable right away. The built-in coil spring and damper do a solid job absorbing bumps and vibrations. It takes that harsh “jolt” out of small cracks and uneven surfaces and turns it into a much smoother ride. It’s not full suspension, but for something this simple, it makes a big improvement in comfort—especially on longer rides. Installation was straightforward—just make sure you get the correct diameter for your bike. Once installed, you can tweak the firmness using the adjustment screw on the bottom, which is helpful depending on your weight and riding style. What I like: * Noticeably reduces road vibration and small bumps * Adjustable stiffness lets you fine-tune the feel * Lightweight aluminum build feels solid for the price * Quick, easy install (a few minutes) * Great value compared to higher-end suspension posts Things to keep in mind: * Not as refined as premium suspension seatposts * Adds a bit of weight compared to a rigid post * Seat clamp adjustment could be more precise * Works best when paired with a comfortable saddle For me, this turned a slightly harsh ride into something much more comfortable without spending a lot. It’s especially useful if you’re riding longer distances or on less-than-perfect roads. Bottom line: A very worthwhile upgrade that significantly improves ride comfort at a budget-friendly price—simple, effective, and easy to install.

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

I bought a light weight ebike that does not have any suspension options; my old regular bike has suspension. My regular ride is gravel trails, not mountain trails though. The first ride was rough; it was clear right away that I needed a suspension seat post. Installation was straightforward. The improvement in ride quality was night and day. I can't imagine a more expensive one can offer further improvement in ride comfort. Highly recommended.

We have two high-quality bike's that we ride. The first was made by Dynamic (no longer selling retail, corporate only) that came with a suspension seatpost that makes the bike very comfortable to ride on the broken pavement that our city calls "streets." The second bike is a high-end Montague, with an 11-speed Nexus hub and hydraulic disc brakes. Unfortunately, it did not come with a suspension seatpost, so between the aluminum frame and 60lb-plus inflated tires it rides pretty rough here in town. Did some research and ordered one of DJC's suspension seatposts. The Montague's seatpost down-tube needed a 30mm post, and DJC was one of the few that offered a post in that size (by using a tube-shim). Very easy to swap out and install on the bike. The DJC is very handsomely made, using nice quality aluminum and steel materials, all finished very well. It offers the option to adjust how it reacts to bumps by way of a hex-wrench "nut" in the bottom of the post itself, which alters the tension on a compression cushion inside the post by way of a spring that's compressed by that hex-wrench nut. It's well-thought out, well-designed and well-executed. But we can't use it! Why? Because the DJC seatpost has a large "collar" at the top of the outer tube of the post that the upper part slides down into. This collar stops the seatpost tube from simply disappearing down into the frame tube, so it's a really important part of the seatpost. The collar stops the post by butting up against the frame tube at the "pinch bolt" of the bike frame (the part that "locks" the seatpost at the correct height for the rider). The pinch bolt collar is rather substantial in size itself (making it strong and reliable), so it's also on the tall side. This means that between the two collars (seatpost's tube collar and bike's seatpost frame pinch bolt collar) the seat cannot be lowered enough so that my wife can actually fit on the bike safely to ride it. Obviously, the original seatpost (non-suspension type) didn't have this limitation as it is simply a straight tube that will slide all the way down into the frame. This allows the seat to be lowered all the way down until it's sitting on the top frame tube. So why am I explaining all of this? I want to be fair to the DJC seatpost because it is a very well made and quality product for a great price, but it simply can't be adjusted low enough for my wife to use on her bike. This is a real shame, but it in no way should be considered a negative on the DJC component. We really wanted this to work, but unfortunately it isn't possible.

Night and day difference with this! I have a large heavy cargo e-bike, no suspension, for hailing 3 kids and gear on a daily basis and where I live the streets are full of potholes and bumps which used to rattle my brain but now I ride much more comfortably. This is a very effective, affordable option for dampering bumps and potholes. Highly recommend.

Priced great for this added benefit to my wife's bike. With a nice saddle/seat and this extra suspension, the bike has a smoother than normal ride to it.

reliable comfort. good shock absorption. my only complaint is the pin (hidden by the label) that holds the top bracket to the shaft, sometimes shears from rotation. I blame that on my weight!

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.

This seat post is awesome! I can't believe how much more comfortable my rides are now. The suspension is firm enough to not feel squishy, but is still responsive. You'll still notice bumps are there, you just don't feel them as much. If you enjoy riding, you'll like it more if you get one of these.

It titted my fat tire ebike with the shim, and it's quite smooth, unlike the other cheaper option I tried which I had to return because it was not smooth. Works well so far. There are better options but they are much more expensive.

après un mois d'utilisation , rien à signaler , fait le travail.

Good product. Easy to install and helps with the bumps. It's not the panacea and doesn't absorb all the bumps but makes the ride smoother. Recommended.
