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

I am finally back riding my Trek hardtail and unfortunately when I had my Jeep parked at Home Depot with my bike locked up on the back, some crack head stole my seat and seat post via the quick release. I remember when these type of struts came out but I never saw the need for my style of riding. This post fit perfectly and it is nice to sort of have some sort of shock absorption but to be honest when I am riding rocking portions on singletrack, my butt is never on the seat. But, it LOOKS GOOD and that is worth something! This shipped very fast and high quality!

This seat post is great, especially for the money and installs in literally minutes. You can set the tension on how soft or stiff you want it to be on the bottom of the seat post with an allin key and really works great obsorbing shock. It's a must have on any bike.

This shock absorbing seat post works well.Make sure you get the right size of depter for your bike. Also a note the seat post increases the minimum height of your seat by a few inches.

Superb product for the price. This seat post is a game changer for me. I have two e-bikes. One has suspension, but my new one doesn’t. I purchased this seat post for my new bike. It helps quite a bit with absorbing the bumps. Makes riding it so much more enjoyable. Hopefully it’ll hold up for the long haul. Time will tell.

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.

This is a very good product. I have had it since last summer and the change in comfort was beyond my expectations. The trails and rocky creek beds are much smoother now and I don't feel the beating I got on some of my rough rides as in the past.

worked pretty good

Works ok. Pretty stiff.
