SR SUNTOUR Sp12-ncx Seat Posts

In order to speed up my urban commute while also getting some workout I recently purchased a used commuter bike. On the first day of ride to and from work the road bumps had my rear hurting. Disappointed, I debated returning the bike. There was no way I was going to shell out $$ for a mountain bike (full suspension or otherwise). While browsing the interwebs about cushioned seats, I stumbled upon the suspension seatpost phenomenon. Enter this seatpost. Installed as it arrived, went out for a test ride. Wow! what a difference! The ride was smooth, barely felt the seat move even while going over deeper bumps. As if I was riding a full suspension (I used to own two mountain bikes, a hardtail, and a full suspension). I am so glad to have stumbled upon this, looking forward to pain free commutes and a decent workout!

I know there are tons of glowing reviews for this gadget, but if you're light like me, you probably won't be as impressed. I weigh about 135, and even with the "light"/soft suspension spring in this thing (which I had to order separately from Suntour for about 15 bucks [and which is supposedly rated for people from 100-140 pounds]), the dampening is just good, not great. Specifically: The thing boasts about 2 inches of travel, which is great. But at my light weight, I can only get about 3/4 of an inch of dampening at the very maximum, on a huge bump. So the difference isn't huge. If Suntour—or anyone, for that matter—offered an even softer spring, I'll bet the thing would be awesome for lighter guys like me, or lighter women, but that's not the case.

I NEVER write reviews but this post is AMAZING it is so freaking comfortable. I am 5'11 280 lbs and it is absolutely perfect for my size. There is an adjustment on the bottom of the post for the level of softness or firmness. I will never go without one again. I have had full suspension Treks that dont even compare to how smooth this thing is while you are riding. It is a little on the expensive side in my opinion but whatever, everything is expensive now with all of these greedy CEO's.

I strained my right quad doing the shock absorption on my bike when touring because my bike is quite unforgiving. At age 60 I have done about 6000 miles touring before finally realising I needed to do something about this. Now I can sit down and peddle through even the worst bumps without being catapulted from my seat and my hands and shoulders are taking less strain. I tried it on the worst road near me (repeatedly) where I always had to stand up to pass or I would literally be jolted off the seat, and I just cruise through. It's subtle too, I can keep peddling effectively even as the seat does its job. Really looking forward to my next trip through Europe this year. This merchant sent the seat post with instructions and the neoprene cover. I weigh 150lb and didn't have to adjust it at all.

The seatpost arrived in an OEM bag, no cardboard box, just a plastic bag with the instructions. The materials feel well made, some sold heft to it, great for a commuter or a recreational bike.Installation and setup was easy, just remove your old seat post, install your seat to the rails, and install in the frame. Sit on the bike and adjust to where it feels comfortable and give it a bounce, you're supposed to be at about a 1/3 compressed when sitting on it normally, if you need to adjust it, there's a screw in the bottom of the post to either add or remove the preload. When sitting on it, it does shift the seat back a bit compared to the traditional solid seatpost, but it's only 1-3 inches depending on your weight.On the road, it eats the bumps that rattle the fun out of riding, Well worth what i payed for it. It does introduce the annoyance of having to lubricate the moving bits occasionally, but it's well worth the effort.

I have a Electric Hardtail Mountain Bike with "Big Apple" road tires 28x2.25". I weigh 150 pounds. I just got this seat post the other day. At first I felt it was just a bit springy. Maybe, it needed to break in over a few miles or maybe, I got use to it. You can adjust the tension it if you wish, I haven't yet.I feel that this is a big improvement for my e-bike. Not only do I have greater comfort, but I far have greater control and confidence over street bumps at speeds exceeding 30mph, down steep hills. I especially appreciate it when I hit an unexpected bump.Some people have suggested that you lose some power from the suspension action, that's hardly noticed by me. I haven't tried other suspension post, so I can't say this is best out there. I will say that I'm very happy with this purchase. Please note, that the SR Suntour SP12-Ncx Seat Posts will be heavier than your original post.Update I placed this post on my rigid frame 28mph pedal assist road e-bike. The currant tire are 700c x 40mm. What a huge difference in comfort and handling. I tuned the post to the softest setting. I highly recommend this post to anyone who has a hardtail bike.

Diese ist wohl die bei weiten beste Sattelstütze, die wirklich schön abfedert aber sie hat einen gravierenden Mangel.Der Sattel ist nicht waagerecht einstellbar, entweder ist er vorne zu niedrig oder zu hoch......man kann was man will man bekommt es mit dieser primitive Sattelbefestigung nicht hin.....Amazon und ich können ein Lied davon singen. ich habe sicherlich mehr als 10 Sättel probiert...never...kann man machen was man will.Mal einen schönen Gruß an den Hersteller: ich bin nicht der einzige, das das Problem hat, den Sattel in eine Waagerechte zu bringen...Problem erkannt? ...macht auch nicht, meine habe ich an Amazon verbittert zurück geschickt!Sehr schade drum!!

So, post a bit of a mix up on delivery, the Suntour NCX suspension seat post arrived (Prime next day') quickly and safely. First impressions were good, it appears very solid and well-built, nicely finished with bright white logos and lettering on a matt/satin black finish. One thing I noticed immediately, however, was just how much heavier this seat post is compared to a standard, non-suspension, post. Of course all suspension seat posts are heavier to greater or lesser extent but this one is on the greater side of things - the tough parallelogram design comes at a cost on this account.This aside, the design is visually pleasing, it looks and is robust, and is well finished. The clamp is designed to accommodate 7mm seat rails and secures the seat via two wide flange stainless steel hex bolts either side. Leveling the seat is achieved by loosening these bolts and 'clicking' through notches in the clamp incrementally. Consequently, getting the seat perfectly flat, if that's your thing, can be a little tricky. Otherwise the post dropped cleanly into the seat tube on my Marin hybrid and all was well. One thing to keep in mind here is seat post length. I ordered the 350mm (27.2mm) but there is also a 400mm option available - which may be important if you are tall and on a small frame (I'm not). Also be aware that the parallelogram itself takes up about 3-4 inches of the seat post length so if your present post drops further into the seat tube than this it might be a problem.Another inherent consequence of the parallelogram design is that as the seat compresses, both under the rider's weight and when soaking up bumps, the seat naturally shifts both downwards and backwards. This therefore needs to be kept in mind and accounted for when setting up - the post should be set to ride at the correct height with the rider is seated and the seat itself should be set at the correct distance forward or back under load. This latter adjustment was a potential problem for me as I am short, with a short reach, so I will typically put the seat more forward on the rails in any case. Getting this in the right ball park meant setting the saddle pretty much at the limits on the rear of the rails to get a sufficiently forward position. I don't think this will be a problem for most riders however, I mention these things here because they might be useful to those, like me, that are short of stature, and reach., in which case some compromises may be in order.On a more positive note, I was pleasantly surprised to find that the NCX suspension post comes not just with the possibility of changing the spring for one with a higher or lower rate (stiffness, the standard spring is medium, good for up to 95kg riders apparently) but that the screw that retains the spring in the tube, like some other suspension posts, allows for adjustment of the preload. The one I received had the spring pretty well loaded up (i.e. tightened so as to give quite hard ride) and I had to back it off quite a bit to get to the 'sweet spot' for me. This of course doesn't actually affect the spring rate, only changing out the spring will do this, but it does change where the suspension starts to take notice of the lumps and bumps on the trail so it a useful adjustment to have. This is also useful if you want to control the amount and frequency of the seat shifting in response to trail conditions (given, as above, the action of the parallelogram when functioning).Once, set-up and with a good bit of static trial and error bouncing up and down on the seat to check it was working more or less as intended (e.g. that it hopefully wasn't going to bottom or top out, etc.) it was time to try it out for real!Riding on a mixture of tarmac, dirt, and gravel roads, as well as some woodlands this suspension post really does perform much better than any of straightforward piston type affairs I have used previously - it's in a different class. I eventually found that what worked best for me was to set the preload so that the sag, with my weight actually on the seat, allowed the seat to 'float' around a third of the way down the suspension travel. This way I found it really soaks up a lot the holes and in the roads and rocks off-road without hitting the top stop on return. This might actually a bit too 'bouncy' for some but at this point is a matter of personal choice.What I can say though is that, generally, the NCX exceeded my expectations and it is certainly a good value option if you want life in the saddle to be a bit more comfortable but don't want full suspension or an armchair for a seat. In fact the saddle on my new Marin (stock) is a bit too harsh for me and I was going to change it, I probably still will, but the NCX makes enough difference that it's now more a matter of choice than necessity. Does it work as well as a full suspension bike? of course not, no where near really, but it's a great alternative for softening a down side of hard tails whilst keeping all the benefits. Overall shock absorption is very good for a suspension seat post in this price range, indeed in any price range. Is it worth the money, is it worth the investment? Absolutely.Pros: Cons:1. It works, very well! 1. Heavy (relative to a standard post)2. Good build quality and finish. 2. Could be tricky to set up for some.3. Changeable springs and (therefore) rates. 3. Dust cover not supplied (available separately)4.Well priced against similar products (e.g. 'Thudbuster')In conclusion (and having only had it a very short while) the Suntour NCX suspension seat post has really impressed me. It works better than I thought it would and although it may not be for everyone I found it transformed the ride and feel of my hybrid in a very positive (i.e. comfortable) way. It looks good, soaks up the lumps and bumps, and the price, whilst not cheap, doesn't cause palpitations the way some bike upgrades do these days. The dust cover should come as standard, as should a choice of spring rate, and I'd have liked to have seen finer adjustment available for seat leveling. However, this is a great product, I love it, and happily recommend it.

Also so gut die Federung auch ist, gibt es ein großes Problem:Die Aufnahme für den Sattel ist viel zu weit hinten. Da die Federung nun auch noch nach hinten federt, sitzt man noch weiter hinten. Ich habe den Sattel in der Halterung schon so weit wie möglich nach vorne geschoben aber auch das reicht nicht. Ich bin 1,83m groß.Dieser Umstand tut mir echt am Gesäß weh. Sehr schade darum, denn es gibt keine andere in der Preisklasse...Aber es gibt ein Workaround, wie man das ändern kann. Das oberste Teil des Parallelograms muss gelöst und um 180° wieder montiert werden. Dazu muss zuerst am unteren Ende der Stange die Federung ganz auf - (minus) gedreht werden bis die Schraube fast heraus fällt. Nun müssen die Madenschrauben in den oberen beiden Achsen gelöst werden und die Achsen dann herausgezogen. Nun die Aufnahme um 180° gedreht wieder montieren und die Feder wieder auf Spannung bringen. Fertig. Nun lässt sich der Sattel weit genug nach vorne schieben und die Funktion wird nicht beeinträchtigt. Keine Ahnung wieso suntour das nicht gleich so montiert. Außerdem ist nun der Sattel perfekt waagerecht justierbar.

Ich hab die Sattelstütze relativ spontan gekauft, da ich im Netz auf die von by Schulz gestoßen bin.Nach durchlesen von ein per Tests, wusste man schnell, das Preis-/Leistungstechnisch die Suntour SR SP12 genau richtig ist.Ich muss sagen ich bin nicht enttäuscht worden.Habe sie nur kurz zum Testen angebracht und Fein eingestellt, aber der Comfort ist auf Anhieb spürbar auf meinem Haibike Sduro Trekking.Da ich sowieso etwas dazu neige Rückenschmerzen zu bekommen ist es fantastisch.Ich bin über jeden Bortstein hoch und runter, über jeden Gulli und Backstein, nichts gespürt.Klar würde ich das nie machen, zumindest nicht im Sitzen, aber ich wollte es wissen.Vorher musste ich jedoch 3-4 mal die Feder fein einstellen. Denn eine viertel Umdrehung macht schon viel aus, ob es zu weich oder zu hart vorkommt.Wichtig ist, bitte richtig herum montieren, theoretisch geht es auch falsch herum dann passiert nichts, hab ich in einem Video gesehen :DBei einem Preis von knapp 56€ kann man nichts falsch machen.Eigentlich wollte ich zu meinem Großhändler ums Eck (Kalker XXL) aber als ich den Preis gesehen habe von 99€ fand ich das schon unverschämt.Bei einer kleinen Werkstatt verstehe ich sowas noch, aber nicht bei den Großen.Mal abgesehen davon das man für den Preis schon bessere bekommt.Nunja kann es euch empfehlen, top comfort, wie lange es hebt, werde ich sehen.Ich nutze es jeden Tag, also sollte sich was ändern editiere ich :D

Nicely designed and manufactured suspension seat post. I purchased this after my previous suspension seatpost (an earlier version of this one) developed too much play in the joints after 5 or 6 years of light use. This version either has a stronger spring or the geometry is slightly different which means, at 70kg, I appear to be at the lower weight limit. I have the spring adjustment set to minimum compression yet it still doesn't feel as 'floaty' as my previous Suntour suspension seatpost - it feels a bit stiffer. I've seen replacement springs available with different compliance ratings (both softer and harder than the, I assume, standard one supplied) so substituting a different rated spring is an option. I find isolation from the road/track surface is still good and there's no play whatsoever in the joints - of which there are many. I understand that replacement joint bearing kits are available for this model. I hope they won't be needed for a few years yet.One thing to watch out for is that the suspension mechanism makes this seatpost sit very high. Some riders may find that, even when the seatpost is set as low as possible into the bicycle's frame, the saddle is still too high. In other words, if you already use a non-suspension seatpost where the length is inserted approx. 80% or more into the bicycle frame, you won't be able to adjust the saddle low enough with this suspension seatpost.Also, the suspension movement is unusual in that the saddle moves backwards and down in an arc. This means that, when the suspension is properly adjusted, the rider sits slightly further back from the handlebars than normal (at a guess, about 5cm) - which may or may not be an issue for some.EDIT, March 2020: Replaced the supplied spring with the old spring from my previous Suntour SP12 suspension seatpost and this gives me back the near-perfect isolation I had before. A definite improvement. How much effort would it take for Suntour to state suitable weight ranges in their specs? From my experiences, the spring currently supplied with this NCX seatpost is unsuitable for riders weighing under about 70 - 72kg in that such riders won't get the full benefit from the suspension. If you weigh 72kg or less and are using the currently supplied spring, isolation will noticeably improve with the weaker spring.
