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

Bought this product for my Aventon Aventure2 Ebike. Paired it with a YLG extra wide bike seat with seat springs and it's definitely been a game changer on long rides. Very comfortable and takes a heap of the shocks from bumps. Great quality for the price!

I bought the black 31.6” for my Lectric XP 3.0. Fits fine, no shims or sleeves needed. Better quality clamps, better tension adjustment and smoother operating than the “premium” Lectric branded suspension seat post. I set at the min insertion line and at a 3/8” sag. To set sag I put a zip tie around the chrome part of post and push all the way against the main post, then gently sit on the bike and get off to see how far the zip tie pushed up, then measure. Adjust tightness from bottom. I believe the height is about the same as old one. Time will tell, but I’m happy with it!

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 have a 2024 Radrunner 2 electric bike. The seat that came with it was very uncomfortable so I bought a cloud 9 seat and paired it with this seat post. The two together provide a SUPER comfortable seat for long rides on the bike. Just make sure the seat you plan on using pairs with the measurements of the post you are planning on purchasing. It was tricky getting the seat post onto the seat at the right angle, but once I figured it out, it went pretty easily. Instructions are pretty minimal so plan on using a lot of intuition when installing.

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.

For the price an excellent value. Improved my ride immediately, Only thing I would recommend is better instructions on how to adjust for riders weight

Arrived as scheduled, the stem and seat were easy to assemble and the included shim worked great

Easy install and comfy ride. Top mounting bracket could have been a little bigger for tighter hold

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.

Excellent quality but expensive.

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.

Great for reducing bum and spinal discomfort across uneven ground. This Schock absorbing seat post adds comfort without sacrificing pedal and rolling power, like front fork shock absorbers do.

Works well. Easy to fit.
