Review: Highly effective at smoothing out the bumps and saving your back - First I put one of these on my e-bike, and it made a big difference in the ride. The bike has front shocks, but I was getting hammered through my butt and my old back didn't like it at all. After some research on seat post shocks, This one seemed like a good compromise between performance and cost. It exceeded my expectations for performance, and within a week, I decided to replace the old seat shocks on both my wife's and my hybrid bikes. In both cases, the improvement was dramatic. I highly recommend these seat shocks. Review: Game Changer! - I have a few bikes. Hard tail racer, full suspension MTB and an E-Bike. I have lower back issues and recently after riding my E-Bike I felt more pain than I usually would. So, I pulled the pin and fitting this suspension seat post to the E-Bike. I've done a few 50 km days riding to work and back and this seat post is a game changer. I have no pain while riding and none post riding. I'm a heavy guy, 115 kg and the stock spring has enough to keep me at 30% sag. It hasn't bottomed out once. I do know you can buy a heavier spring for this seat post and for my weight I was supposed to according to the booklet. However, that must be for extreme use. I'm commuting on paved cycle tracks. ## Features - SIZE: 27.2mm x 350mm (PLEASE DOUBLE CHECK YOUR SEAT TUBE SIZE BEFORE PLACING ORDER.) - Make sure to measure the diameter of your old seat post before ordering - Travel: 50mm - Length: 350mm (Maximum extension of 300mm height) - Preload adjustable - Suggested rider weight: 60 ~ 100Kg ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FT931BP | | Brand | SR Suntour | | Brand Name | SR Suntour | | Colour | Black | | Country Of Origin | USA | | Customer Reviews | 4.7 out of 5 stars 1,137 Reviews | | Item Diameter | 27.2 Millimetres | | Item Dimensions W x H | 27W x 350H Millimeters | | Item Weight | 0.87 Kilograms | | Manufacturer | SR Suntour | | Manufacturer Part Number | T180601 | | Material | Aluminium | | Material Type | Aluminium | | Model Number | T180601 | | Mountain Bike Type | Mountain Bike | | Product Dimensions | 27W x 350H Millimeters | | UPC | 714497214382 | | Unit Count | 1 Count | ## Product Details - **Colour:** Black - **Item Weight:** 0.87 Kilograms - **Material:** Aluminium - **Brand:** SR Suntour - **Product Dimensions:** 27W x 350H Millimeters ## Images ![SR Suntour SP12 NCX Suspension Seatpost with Protective Cover (31.6) - Image 1](https://m.media-amazon.com/images/I/51OC+5L32XS.jpg) ## Questions & Answers **Q: What is the minimum distance from saddle rails to the post bracket?
