Title: Well worth the investment
Review: Application: Female 72 years, 5’5” ~133 lbs reasonably good physical condition and athletic; with total hip replacement in last 12 months.Purchase this seat/saddle post to be used in with new e-bike we are over 70, and with age it is important to search out best in class products to help mitigate ride discomfort during and after the ride. In addition to the active post I purchased a saddle upgrade from the OEM supplied with the e-bike which was Terry Cite C Gel Italia which is a Touring design you will find my review on Amazon.The SP12 NCX is very robust in materials of construction so do not see any potential for premature product failure. Great value when compared to cost of rear suspension bike.Important points to check and consider:Rider weight will determine the spring compression rating the post is supplied with the standard spring140-180 lbs, there are two additional springs sold separately Blue 140 lbs or less and Red 180 lbs + ~ $25 for optional spring see SR Suntour North American website for more information and purchase.Identity your vertical ID of the bike tube receiver you can measure or better see you bike owners manual. ID make up sleeves can also be purchased.You will need 5mm Allen Wrench to install the seat to the post. Important that you visually confirm you have “full contact of the saddle/seat bracket with the two halves of the post clam” and once in position tighten to 15-18 Nm.(11-13 foot pounds) Vitally important for your safety that the installation is secure.You will need 6mm Allen to adjust the spring preload or for spring exchange . The default load is ~ 50% of full scale.To maximize the performance and benefit of the product you need to choose the correct spring and potentially adjust the spring preload. Their is 50 mm (2”) of post travel ideally you want to adjust the spring to utilize the maximum travel.For your safety… If you do not have the correct tools or not confident in your ability to install correctly have a professional perform the installation.There is no scaling on the posts that said once you determine the ideal height position mark the post by wrapping electrical tape around the post tube so you can reinstall at the same height.Only negative I see in adding the post is weight 765 g or 1.69 pounds however if you are installing on an e-assist bike it is not necessary important factor.Combination of upgraded saddle and suspension post delivers a superior riding experience. For best experience do your research there is more to understand and consider the above is a summary based on our experience.No I do not have a suspension seat post because I ride an e-assist recumbent tadpole trike with full suspension, or I would.Enjoy your ride and do so safely.

Title: Great seatpost.
Review: Compared to the Kinekt (~$270) or stock suspension seat post I had, this is much better for the money. I put this on a Rattan LM 750 Pro. I do wish they offered this in 30.4, but I just got a shim to bridge the gap between 27.2 to 30.4 and so far it works just fine. It’s easy to install, comes with a cover for the moving components, and feels smooth when navigating bumps. I also wish they would offer one that can support riders of up to 250lbs. I’m 6’ 230lbs and would feel a little better if I was within the listed weight range of this seat post, which is 100kg (~220lbs). Make sure you adjust the tension to suit your weight, decrease for lighter riders, increase for heavier. Now I just need a better seat.

Title: NO Cover, well constructed, easy to install. Heavy spring not needed. Good Instruction booklet.
Review: Seems nice, rode for 10 minutes, really softens the bumps. Also bought the heavier spring as I am 215 lbs but rode with the medium spring and it seems okay. Will return the HD spring. Did not come with the cover. Contacted Suntour and they replied that I would have to contact the seller. As yet have not been able to contact them. They don't seem to make it easy to contact. Maybe a company rep will see this and do the right thing.

Title: Like having full suspension
Review: This suspension seatpost is worth the money. I tried a $20 "pogo stick" style seatpost and it took the edge off the big bumps but was only a minor improvement in comfort. This one is several times better at absorbing bumps, big and small.

Title: Good value, plenty of travel
Review: I have several bikes, but because of the years and miles on my body, I decided to try suspension seatposts to take some of the shock from my lower back. I purchased several seatpost styles and brands to see what works. The bottom line for the SR Suntour SP12 NCX Suspension Seatpost is that it has excellent compliance and is very adjustable. It's a little heavier than some of the others, but this seat post works well and just sort of disappears under you, and it has plenty of travel. The spring is steel rather than an elastomer, so response to input from the road or trail is immediate and the method of adjusting preload allows fine tuning. The fore and aft seat adjustability is limited by the mechanism, but that may just be my bike. The only criticism I have is the installation. This was the most difficult seatpost to install that I purchased, and you definitely have to follow a sequence of steps that aren't obvious the first try. The way the saddle attaches to the post is quirky and a little aggravating. But once installed this thing works like a charm and I'd buy it again - as a matter of fact I did. I bought a second one for another similar bike and the second install was easy. I consider this seatpost to be a modest compromise in aesthetics and probably the best value of the bunch. One last thought: don't buy a telescoping seatpost; buy the parallelogram style, whatever brand you get.

Review: this is FANTASTIC! So easy to install, such a soft ride now, it’s better than expected. Works good on ebikes. Nothing negative to say. I really like it. KEEP in mind it does add some height to the frame, a couple inches, so might not be good for short people to be up so high, but it is a great addition to bikes for a much softer ride.

Review: The cycle path I use in Melbourne is far from smooth and I was getting lower back pain.The shim I ordered to fit the 27.2 post to the 30.0 mm tube was the wrong size, but I was not required to pay for it and I re-ordered. So I had to wait a while to fit it.An amazingly smooth ride now. Even big bumps and dips, I don't feel. The bike does, but I don't.Never written a review before, but I felt compelled to give credit where it's due. This product does what it claims to do and is easy to fit (when you get the correct shim ,if you need one).

Review: This seat post makes a world of difference in the comfort of a rigid frame road bike. There are some neglected roads in my neighborhood with bone-rattling bumps that I used to dread riding on, but after installing this seat post, I barely feel them at all. It's made riding so much more enjoyable. I just wish I had the option of buying it with a heavier spring instead of having to purchase the upgrade separately.

Review: I used this along with a cloud 9 saddle on my radrunner plus ebike. The difference in comfort from the stock seatpost and saddle combo is night and day. This seat post works great on reducing the bumps when I hit pot holes. Easy installation. I am a heavier rider and exceed the recommended max weight limit for the stock spring but it works well for me.

Review: I installed this on my etrike. The trike has rigid rear suspension so it’s not comfortable on rough terrain. This suspension post a makes a big difference and it is much more enjoyable now to ride my trike. Time will tell if it lasts, though. So far, it qualifies as a smart purchase and good value for the money.
