REDSHIFT ShockStop Endurance Suspension Seatpost for Bicycles, Shock-Absorber Bike Seat Post for Road, Gravel, Hybrid, and E-Bikes

Having read a number of reviews of the Redshift Endurance Seatpost (and having tried telescopic seatposts), with reviewers noting how it greatly improves the comfort of riding, I was persuaded to buy one. All these claims of comfort are fully justified: this seatpost really is excellent. Initially, I bought one for an electric bike (30.9mm), which was such an improvement on the rigid post that I bought a second for a non-electric hybrid bike (27.2mm). As many others have observed, the seatpost smooths the ride over bumps to the extent that they become simply undulations and not a bone-jarring experience. There are a range of rider weight-related settings, adjustable for comfort, helpfully listed (as a starting point for fine-tuning) in the seatpost's instructions. In terms of softness, the aim is to ensure there is no excessive 'bottom-out' when riding over uneven roads/tracks. The settings I've used are based on my weight with the rucksack (toolkit; spare inner tubes; etc.) I carry on all my rides: 84kg. 30.9mm seatpost setting: '4'; 27.2mm seatpost setting: '3.5'. Highly recommended.

This seat post is a game changer for me... Comfortable for miles and miles... Brilliant piece of kit 😄

My road bike already had headset suspension for the bars which helps avoid numb hands, but with country roads around here being so damaged, I was looking the something to help soften the shocks at the back too… The Shockstop seatpost is clearly very well and thoughtfully engineered, and that’s clear both as you take it out of the box and if you watch the detailed and thorough installation video that Red Shift have put on YouTube. The most fiddly aspect of installation is probably swapping the saddle over from your old seatpost but it’s really not tricky at all. To get the best out of it, you need to adjust the ‘preload’ for the spring (or rather springs): too soft and you’ll bounce a little too much when pedalling hard. Too hard and you won’t get enough benefit for smaller bumps. This is adjusted by turning a large screw at the bottom of the Shockstop seatpost - you can use a small screwdriver or Allen key if it’s too stiff for your fingers. There’s a guide in the box for an initial setting according to weight, but it’s more of an art than a science and the right setting will also depend on what type of surfaces you mostly ride on and your posture on the bike. Heavier riders (myself included) will need to use both of the included springs to be able to set the correct preload. For me, it took another two tweaks after installation to find the perfect ‘Goldilocks’ preload for me and my bike. And the result is great! Before getting this, I would definitely think hard before doing all but the smallest rides without padded bike gear, but this honestly adds enough comfort for trips to the shops or pub in normal clothes without your bum complaining. ;) It’s not a miracle cure for bad roads, but it makes a bigger difference than I would have expected and for me at least - who rides for fun and exercise rather than racing - it’s well worth the extra weight for the massive boost in comfort especially over longer rural rides.

I am impressed! I just fitted my new Redshift suspension seat post and took a test ride on London’s bumpy roads and streets. The absorption of uneven ground is magical! It was not easy to install; I have to blame my saddle, not the Redshift seat post. The fitting and adjusting options are great, the cost is high, but it is worth the investment.

Works well to iron out some of the harsh bumps on UK roads. It states its 350mm long but its more like 380mm so I was worried it wouldn't fit in my small frame without making the seat too high, but its fine. Would definitely recommend.

I considered buying a seatpost for a long time, considering the relatively high price of the Redshifts Endurance, but I finally decided. My first impressions are positive. I like that it's not as bulky as other manufacturers. I also rate the build quality as high. I can't comment on durability because it's a recent purchase, but other owners rate it as good, so time will tell.

If you would like to improve the comfort of your ride this seat post is for you. I’ve been riding road bikes for years and have a lovely bike sitting in my hall but which I couldn’t face riding to work or for fun/exercise because of the harsh ride and poor roads. I thought a change of saddle might help but I’m so glad I went for the redshift seatpost option instead. All bone jarring road impacts, big and small are cushion by the suspension to such an extent that I’m excited to ride my bike again! Read a few reviews first and managed to dial in the correct tension for me straight away. I’m 80kg 6ft tall and riding a road bike on roads, I used both springs set the seatpost to number 2. There was a very slight bob on small climbs but you could can easily stiffen the setting slightly if you’re planning a lot of hills. Definitely the best upgrade I’ve ever made to a bike and actually road through a long bumpy road that was waiting for tarmac, seated, without discomfort. You also no longer have to constantly put your weight on the pedals, stop pedalling and raise yourself out of the saddle over bumps to protect your backside. Sleek for a suspension seatpost and looks top quality. Unless you’re a competitive racer I’d say this was a no brainer and well worth the money.

Really does smooth out the road. The road on my commute is so bad I was considering wearing a gum shield to stop my teeth rattling. I can now comfortably sit on my saddle and ride those bumps. It’s like riding a new bike. No bike should be without one.

I used to use a Thudbuster and loved it for 20 years. Then my mountain bike frame cracked and I moved to a full carbon gravel bike. Recently some cretin stole that bike so I bought an aluminum city bike. I used to own aluminum but forgot how unforgiving the material is until I took this one out on the streets of Tokyo and felt all the chatter and bumps through me. So I decided to invest in this product and I could not be happier! It was super easy to install, it already came preloaded perfectly for my weight and slid into the seat tube smoothly. The saddle bindings are unique and we’re not at all difficult to adjust, making getting the saddle angle just right, a snap. Suddenly I feel like I have rear suspension again! The road chatter is gone and the bumps and divots smooth right out. I look forward to many years of riding with this product. The team in the US was great, very helpful, responsive and a pleasure to work with. They answered all my questions and more so I am very happy with the service as well. Thank you Team Redshift Sports!

I enjoy every mile with it. Saves my back.

Excellent product & service.

Es caro pero vale lo que cuesta.

This is my 3rd order from RedShift Seatpost Suspension. Did ride with the first purchase for more then 1500Km and still keep goin without any issue. You can read more review from internet but here are my personal views base on my own experience without bias. Advantage: 1) Enhance your riding experience. The suspension will soak all the small bumps and small vibration from your rear tyre. 2) You will clock in more mileage due to induce fatigue. 3) If you have any back pain issue and wanted to ride, this seatpost for you. 4) Zero maintenance. 5) Every single ride will make a big smile on your face. Disadvantage: 1) Weight penalty, add more weight to your bike, around 415g for 350mm & 380g for 280mm.(Specs taken from Redshift website) 2) Pedal bob effect reduced your power transfer. 3) For adjustment, you need to removed the seatpost. 4) Design only for circular seatpost and not for aero seatpost design. 3) Expensive for single component. Hope this will help you guys for the purchase.
