    Absolutely! These guys are trying to fix unfixable issues - they had some runs where the bushings/seals were not within tolerances causing all the headaches. SEND IT BACK and get the right parts (what I did) and PROBLEM SOLVED. Now I just have to occasionally pack slick honey under the cap and that's it! 2 seasons and going strong with no taking apart/maintenance!

    Have FUN!

    DU bush not sitting flush.

    Hi Guys,

    I recently got a KS i900 seatpost 2nd hand for a steal. The post running up to the seat clam does have some scoring from the old roller bearings, but from what I have read this should not stop the post from working (perhaprs just not make it as slick as it should be). I've replaced the bearing, brass guides and the DU bush. The post now works again

    The issue I'm having is that the DU bush does not sit flush with the main black outer seat post, there is about a 5mm gap. As a result the red cap does not screw down all the way & when the post is fully compressed the seat clamp reaches the red cap (and seal), which is not ideal. Has anyone else had this issue and is there a way to remedy it? I've checked & made sure that the bearing is fully seated. Apart from that the post is operational, but I'm not comfortable using the post with the bush not sitting 100% flush.

    Hey All, I think my 30.9 post is blown out. It is sinking 1.5" like like a suspension post would. So it comes up to the correct height, but then when I sit on it with any weight what so ever if drifts down. Is there any home repair I can do for this?

    Meanwhile I had sent my 27.2 version off because it was doing the same thing, plus it had a lot of side to side movement after 2years. Finally the post came just came back after like 2 months, and the sinking if fixed, but it still has the side by side movement! I think they must have missed it because you only notice the substantial side to side play when the saddle is installed. Is there a way I can repair either of these problems myself? I now have two posts that don't work correctly!

    I actually have a 3rd, a 31.6 KS post too, but no bike for that one!

    Send them back to Rick and make sure they fix 'em. No chance you will fix them by yourself.

    Been there, done that.

    Thanks, Rick has been great but they didn't have the parts for the 27.2 and it meant I didn't see it for 2 months. Meanwhile it's still usable so I'm reluctant to send it back because I can't find any others in the meantime. I have no choice with the 30.9 I guess, but I was hoping...

    i did not remove my saddle to have leverage and tried to tightened the blue nut a little bit more , then loosen it again... try that over and over again eventually you can loosen the blue nut or even the red cap. but sometimes all you need is the blue nut to remove the shaft from the body

    I have a problem with my KS Dropzone. It will go all the way down but then it creeps up about 1.5-2 cm. Is there a quiq fix for this or should I send it back to the reseller?

    pumping the things up

    When rebuilding these things in my opinion by far the most difficult part is getting the air back into them. Last night I had an epiphany (not an ellsworth). This is probably dangerous, you have no idea what pressure you put in but my is it easy to pressurise the post. With the bent needle, some heat shrink and being able to hold the needle in the hole easily (no flexy hose) I was able to pressurise the post first go. It had too much pressure, was difficult to compress and returned like a rocket so I bled a little gas out by turning out the silver cap you put the gas in through. It's working fantastically now, probably still a little firm to push down but return speed is great and the top out thud very reassuring. It's a CO2 can that you pump up tires with.

    Mine has started to do this as well. Has anyone fixed this issue on its own or is it something you have to send in for service?

    I also posted in the LEV thread before seeing this post...

    Don't want to steal this thread but... I've been trying to get a part: the DU bushing for a 31.6 supernatural and the local distributors don't have it. I'm in Canada if that counts. I damaged the bushing after it fell off my workbench and spent some time on the floor... the thin bushing with the teflon is scrap now... If anyone has a spare or knows where there is one (for real!), please let me know.

    Also, I just bought a new 27.2 supernatural for my other bike and the remote is a lot harder to push/activate than my 31.6. There is nothing wrong with the cable and housing front to back, I checked and double-checked. I don't know if there is a solution to this issue.

    Thanks,

    Johnnydrz

    For what it's worth, I rode my bike yesterday and half way through my 12 mile ride the play went away. I checked this morning and still no play. Maybe it has to do with the way I was storing it (hanging on my garage wall by the front wheel with the seat post compressed)? Last night I left the post it the extended position leaning against the wall.

    Hello, my dropzone has become very stiff 1,5 cm from the top position and stops there.
    I tried to increase the air pressure but I had no luck because the air stucks into the pump and does't pass through the small pinhole. After some posts of a forum-member I noticed that the seatpost works fine when the top red cup is completely unscrewed. But when I screwed it even one turn, the problem rises again!!
    What should I do?
    Do you believe that the trick with the two holes under the bottom red cup is the solution?
    Why is happening now and not when I bought it?
    Ιs there a possibility to create a bigger problem if I drill the two holes?

    Anyone used a spring under the seat lever to help return it to locked position?, mine keeps sticking. New cable and used a mud lover cable outer to try to prolong it life.
