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

Fits perfectly and works well

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.

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 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.
