    Caution;  Merge;  Workers Ahead! KS i950 adjustable Seatpost specific thread

    "Pure Racing Presents KS Technology i950 series height adjustable seatpost for perfect pedaling performance whatever the terrain."

    I haven't seen much out there about this seat dropper . There are a couple of threads here and there, and a lot do discussion on the general thread "adjustable seatpost".



    I believe a specific thread for this adjustable seatpost (model 2010 onwards) is not a bad idea, in fact, it may be required , no only by riders which potentially want to buy this post, but also by current/past owners, to share experiences, issues, questions, solutions, tips, and such.

    So I invite you all current owners to post your thoughts.

    I for my self can only say, that I cant wait for mine to arrive.

    I hav e had one for 6 months, never had to touch it for maitenance. The only thing I don't like is the mounting system for the seat rails, they work and I have never had troubles I just think it is an old school design. The new 2012 ones have a simular seat post clamp system to the Thomson's which is sweet.

    While I agree that the mounting system is a bit harder to get your allen to, but I'm not a big fan of Thomson style 2 bolts either. For some reason it seem to creak more than other design.

    I like the one bolt style like Maverick SB/Bontreger it's easy to adjust.

    Oh, and I have my 950 for over 1 yr and so far not an issue.

    Hi Guys,

    Would anyone know where I can buy the colored remote kits (specifically the blue option) online? I've been trying to look for one but can't seem to be able to find an online shop selling them.

    Thanks in advance for the replies bros!

    thumbs up

    I love my KS i950!
    One year and going strong. Rock solid.

    I used a V-brake noodle at the remote to get a cleaner cable line on my bars:

    I've had mine for almost one full season. I've never had any issues with it...the only challenge has been figuring out the routing of the cable on my Reign 2 so that the cable didn't end up rubbing or hanging out. I have it sorted out now and am very happy with it.

    I just bought a ks i950r. Putting it on a new Nomad.

    Does it make any difference if the cable is in the front or the back? It seems people do it both ways. Presently, I have it out the back, but it looks like it will rub the cable on the tire at full rear suspension compression.

    It seems to me that more often than not, you will see the cable routed up the back of the post. I have tried mine both ways, and found that despite the fact that they're supposed to be zero offset, the seat can be slid further back when the post is turned to have the cable running up the rear of the post.

    There is a picture a few posts back showing a Santa Cruz with the 950 on it. It can be a bit of a hint about how to route (or at least experiment with) the cable. I had to fiddle with mine for months before I figured out a routing method that minimized the issues.... Don't be afraid to waste a few zip-ties experimenting...

    Hey, I have the i950 on my Nomad. Cable mounted in the back.

    What I did was take a plastic coaxial clip :

    ... and w/ Goop adhesive glued it to the upper pivot area. This limits the cable housing movement when you drop the post.

    You can see it here:

    As far as maintenance goes, use a bit of full synthetic motor oil (I use mobil-1 5W-30, same as used on my Fox fork) underneath the aluminum bushing, which is accessible by unthreading the red top cap and subsequently extending the post. Coats and clings better than slick honey, and lubricates just as well, if not better.

    does anyone know if there are color kits for the KS i950?
    I mean I wat thinking on using gold bits on my sand colored 2008 Giant Reign, but if I do so... the red on the KS will look somewhat weird.

    My wife had 2 (she's now on her third) Joplin's. The first one got warrantied once or twice and always would play and then wouldn't stay in place (either up or down). Keep in mind, she coached for a camp sponsored by CB. The new(er) one had the same thing with play. The newest one is ok so far....fingers crossed!

    My KS has been great with a lot of ride and tons of mud caked on it during the wettest winter/spring/summer we've had in the PNW. I probably need to change the cable/housing as that's getting sticky now, but otherwise flawless.

    Check out this guy's walk-through:

    http://www.watermanatwork.com/Land/C...eatpostService

    The only caveat is that you don't actually need to unthread the red bottom cap (with the holes) in order to disassemble the post. It makes doing a thorough cleaning much easier, but it is quite a challenge to remove. If you are dead set on removing it, I would clamp a pair of pliers in a vice, fit the plier ends into the holes and rotate the post while keeping downward weight on the post (so the pliers don't slip).

    If you want to do a quickie without disassembly, make sure you get your grease or oil underneath the aluminum bushing housed under the red top cap, not above it. The bushing should come up with the shaft when you extend the post with the red top cap already unthreaded and out of the way.

    The only other thing that may require regular maintenance is lever actuator assembly built into the seat clamp. This place can get quite grungy and make the operation not-so-smooth. Clean it out however well you can--I use pressurized solvents such as brake cleaner. Then lube the actuator pin (the dome shaped piece that protrudes from the shaft) with oil, it should feel smooth upon pushing it with an allen key. Finish off by greasing the area thoroughly, especially where the red lever meets the actuator pin.

    So far, 4 months of daily use in the wet and muddy, and now dry and dusty without too much issue, although it does require a fair bit of maintenance along the same frequency interval as a fork.

    EB,
    When I rebuilt my 3R, I use 20/50 motor oil, and I overfilled the oil by 1 or 2 cc. The thinking was more viscous oil to help seal things up, and the overfill is so the valve is completely submerged all the time, so the force the air exerts on the fluid exerts will again help seal things vs just air. So far so good, but it's been primarily sitting w/ only 2 rides on it.

    As for KS, if they publish steps on how to get in there, I'd go and hack/mod mine in a heart beat! Same w/ the Reverb (to reduce the extension to 4").
    Naysayers never apologize. Critics go to their grave thinking everyone else is wrong.

    KS-950i One year and it is amazing!

    I purchased a KS-i950r a year ago and it has been fantastic. I originally got it for safety- to keep me from going over the handle bars when taking steep descents. What surprised me was that it made long mountain bike trips more enjoyable. Slight adjustments in seat position make 3+ hour rides much more comfortable on bottom and back. It is also great for keeping a low center when riding single track. I shift seat height almost as much as I shift derailleur. No problems with the system at all, and the 5-inch adjustable is perfect for my 6'2" frame. I purchased a snake skin cover to keep the post clean and add a very small about of teflon lubricant to the post. I would definitely recommend this product: I can't imagine mountain bike riding without the option of adjusting the seat post.

    The i950 does not have a seat clamp offset, the i900 does.

    ... and if we just ... Never again.....

    .....will I ride All Mountain, XC, Trail, Enduro, whatever you want to call it.... without a Telescopic Seatpost!!

    I did a fast round yesterday 12km, I didnt stop once is so amazing to ride with one of these!!!


    There is one but though, Ive read lots about the play the seatclamp has, well, one ride.... and after 30mins I could feel a small play, by the end my seat was all the way forward.
    I have an idea how to solve this, ill post it once I try it.

    I love the hint about using 5w30 synthetic engine oil on the bushing. I did that the other day, cycled it up and down a few times and it's now working better than new.

    Hi all, anyone know where I can get the cable stopper - the one that attaches to the end of the cable and holds the lever under the seat? Just lost mine, without it lever won't work

    Thanks!
    --
    If I work to pay for my rides - then why am I at work right now??
