Suntour Federsattelsttze SR SP12

This suspension post is excellent. It no longer has brass bushings - they are stainless steel and I def have the newer version. I believe it will be just as good and probably exactly the same. At £75 ish it’s actually at the low end of price for one of these and it’s worth every penny. I also have an eesilk but that’s for my road bike.This bad boy is big and heavy and if you ask me is ideally suited to an E-bike hard tail, steel framed city, or anything where an extra kilo doesn’t matter.Really works, very happy.

Having not ridden a bike for about 10 years my 1st ebike ride left me in a fair bit of pain with a bit of a bruised rear.I think the combination of not riding for so long and sitting down for most of the ride which lasted about an hour on my ebike meant I felt every bump as I travelled.Every ride after this was very painful until my friend told me theses existed.I ordered one the same day and received it the next. The whole process of fitting it took about 20 minutes with swapping the saddle being the longest part.Fine tuning the preload was very simple and took a few small rides to get it just right for small and large bumps.I left riding my bike for about 2 weeks till the pain had gone and gave this a proper test ride for about 1hour 30 mins and the ride comfort was excellent. The seat post had removed all the bumps which had lead to the pain previously and made riding the bike enjoyable again.I now try to get out everyday weather permitting that is.I would highly recommend this product and would put it on any hardtail bike I rode again.

Bought this to prepare my road bike for the Paris-Roubaix sportive. Out of the box, it looks like a very robust bit of kit but it is considerably heavier than a standard seatpost. Weight is always important but primarily a cycle component has to be adequately strong to do its job and this certainly seems man enough. Very easy to fit and set up. I found I needed to raise the saddle height about three-quarters of an inch to compensate for the suspension sag. Please note that the paralellogram arms make it more difficult to fit a saddle pack. You can get over it but dont expect your pack to necessarily go straight on. On the road - well only 2 long rides so far but what a revelation. This device soaks up potholes and damps out rough surfaces perfectly. To get the best out of it you have to lose the habit of rising out of the saddle over bumps. I did not seem to lose any power and I would expect, for very long rides that it would help you to go stronger for longer because of the added comfort. The only time it feels a bit weird is when powering downhill over 30mph....bit of a float going on then. But overall, a great product and amazing value for money.

Read a lot of reviews before buying this and took a gamble because it seems maybe this design has some flaws with people suggesting it's a bit bouncy, robbing pedal power etc. Well I have installed this on my Haibike Trekking ebike and my only complaint (which isn't really an issue on this bike) is it's a bit heavy. But it has literally transformed the ride quality of the bike, works exactly as I expected. With the right preload and I weigh about 79kg there is no bouncing and just feels totally natural to ride. Well worth it.

I have heavily customized my e-bike but this is hands down the single best upgrade. It is so comfortable that it brings previously ‘forbidden’ terrains, right in to the palm of your hand. It will transform your riding experience to include more adventures than before. I already have rear suspension in my bike but Suntour’s product will give you another dimension to comfort entirely. Whether you have rear suspension or not, this seat post is a must. What I like is this product is all about keeping you comfy rather than the bike. And it does that better than most products out there. The build quality tells you it’s German and will in all likelihood last a long time. I love to ride my bike just to enjoy the comfort rather than worry about where I am going. I seek out potholes and bumps just to enjoy the seat post!

This is simply a wonderful (and for me) a neccessary gadget.I cycle on average two X 20 mile journeys every week-end, and, although I have a rubber mounted gel saddle, I find that worn, damaged, and washed away tow paths can be a harrowing experience, especially when accompanied with strategically placed tree roots.I wanted something a little more robust than the simple sprung seat post, and I am really happy that I found this product.I was not expecting too much after reading some of the reviews, but I have found this to be so, So, SO much better than described by some.It is very sturdy, and, perhaps, I may be the ideal weight for it [12 stone 8 lbs], for I just removed it from its bag and fixed it into my bicycle expecting to manipulated the settings, but...BUT it seems to be perfect for me.I was a little worried that, because of the mechanism's length, that my seat may sit a little too high, but because the spring mechanism drops about half an inch when you sit upon it, the saddle height became perfect.For me, I can not fault what I bought, and as mentioned above, it IS better than I was expecting.Very happy with my purchase, worth the money; and it arrived quickly too.

Great addition to my bike. Easily installed on my mountain bike and smooth out most bumps. I definitely recommend it to help comfort over rough ground.
