KS i950 Dropper Seatpost

KS i950 Dropper Seatpost 

DESCRIPTION

The new i950 is a revolutionary new seatpost that offers “on the fly” adjustment without the need for tools.

The i950 utilizes a new patent-pending bushing design that self-adjusts, which greatly improves function and virtually eliminates unwanted side-play. With the new KS i950, optimal seat height and performance is just a levers touch away.

Strength:

when it works it is fun to ride

Weakness:

I have it for about 1.5 years, after 3 months of using i had to ship it for fixing, as my seat dropped 2 inches from time to time without me saying so :-) - another 6 months and the problem is back. So now im riding with my regular seat :-(

Need to work on reliability here !!

Strength:

Not the Greatest

Weakness:

Seat Clamp bolts cannot be evenly torqued, too close to shaft.
Sticky on upward travel, but that can be compensated for.

I would not have replaced this seatpost, but for the snap-o-matic seat clamp bolts.
When one breaks the irreplaceable eliptical square washer gets dropped on the trail.

Strength:

looks nice (bling)
solid
lots of travel
reliable so far
remote lever works well (keep lever and cable lubed)

Weakness:

seat clamp bolts

I own 2 of these, one on my all mountain rig and the other on dh/freeride rig. The one on the all mountain rig has been installed now for almost a year and has held up very well. The only issues I have had has been seat clamp bolts loosening and then one breaking about month after I got it. Replacing the alloy bolts with steal bolts and using some thread lock cured the problem.

Second one I just got and replaced the alloy seat clamp bolts first thing. It had a little stiction out of the box, but some stanchion lube has seemed to cure the issue.

Strength:

Excellent remote.

Weakness:

Not user rebuild-able. Poor durability. Horrible customer support.

This dropper was a dream, while it worked, but that was short lived. It only took a few hours before it became a pogo stick. Repeated attempts to contact support have failed. Impossible to rebuild do to design. Very disappointing. I'll stick with my old Joplin which even though has more play and a goofy remote, still works after a years worth of abuse.

Strength:

#1 is customer service. Design, infinite travel, ease of installation, trigger mount fits perfectly over ODI clamp, red anodized trigger is nice looking and ergonomically correct for thumb operation, cost, weight

Weakness:

seat clamp is kind of clunky but works.

I purchased the KS from Outside Outfitters for exactly $239. free shipping, no tax. Installation was simple and easy. At first ride, I immediately felt a small knock when I sat on the bike. Couldn't figure out what it was until I read another review about vertical play. I left it alone for about 10 rides and had no problems with side to side play. But eventually, the post would end up dropping about 2 inches of vertical play and would not hold in its locked position anymore.

I left a message to Rick Taylor who is the US rep. That evening at 7:00pm, I received a call from Ron Easton who is his associate. Apparently there was a faulty batch of internal cartridges and I was the lucky owner of one of them. Ron explained that they would replace the cartridge and that there should be no play vertically or side to side. I shipped the KS back to them for $8.00 via USPS. On the 4th day, I received an email from Ron that the KS was repaired, tested, and on its way back to me. I received it exactly 7 days from the day I initially sent it out! That is what you call great service!

During that time of waiting, I ended up fracturing my Scaphoid bone in my wrist (another story) I couldn't wait to put the KS back on and was able to install it with one hand. So whoever those reviewers say that it took a long time to install the saddle, I did it crippled. :) The KS works perfectly!! Somehow, it seems to pop back into position even smoother than before. And there is no vertical play whatsoever! Not even 1/16th of an inch. It feels like a standard post. Now the question is will it last. I will have to wait 12 weeks as I go into surgery for a screw and healing time to find out. I can't wait to get back on the saddle to fully test it.

Let it be known that a drop seat post is a must and even though I have not tested other like seat posts, I am extremely happy with the operation of this post, the looks are awesome, and best of all a customer service team that backs up their product. 6 Chili peppers if I could! :) Thanks Ron!

Strength:

So much fun. Takes you to another level in your riding style. Beefy construction, Feels strong, Looks Great, So far works perfect (1 ride).

Weakness:

Saddle Mounting - Really are you guys Mtn Bikers??? Come on now you can do better than what is on it currently.

Ok all bikes should have this PERIOD. Yes the price is steep but so much fun. had a Coilair then it got jacked from hB and sold on Craigslist (if you know anyone riding around with a green moster that has scratches on the top tube, it was stolen) ok back to my story. I got the Remedy 8 and wow same travel just so much more enjoyable to ride. Well guess what IT JUST GOT BETTER!!!! Sure I have heard all the stories and honsetly I wanted to wait for prices to go way down. I had a store credit and bit the bullet. So glad I did. I did get the none remote but after my 1st ride I ordered the remote, reason was going downhill I knew I needed to lower but as soon as I was going to take my hand off the bar to reach under my saddle it got steep and bumpy so I had to slow down (pointless). Get the remote and you will not have to think ahead. Okay got 3 more rides this week if anything happens I will write more. If it stays statis quo then this is my post. I am a Clydesdale 6'2 260lbs lets see if I can break it.

Strength:

- Side to side play? What?
- Reliable
- Cable is long enough for an XL bike
- Doesn't creak

Weakness:

- Trigger setup requires some acrobatics with brakes, shifters

I got this because it was as reliable as most dropper posts and had the least reported side-to-side play. I can vouch; this thing doesn't have any wiggle that you can feel while riding at all.

If I don't ride for a while, then I need to 'bump' it from the top a few times before it just starts going down smoothly under weight. It springs back up smoothly and not to quickly (lol).

The only annoyance was setup; to put this on my bars between my brake and shifter I had to unbolt the shifter because the shifter levers were right in the way. Super minor.

Weakness:

seatpost at present isnt staying in position when riding

has anyone with the KS1950r seatpost had issues with the seat not staying up? i have only had the 1 test ride and the seatpost is now back @ the shop being tested. after putting the seatpost to its maximum height then proceeding to ride it would gradually go down. i am 76kg so i dont think its a weight problem. possibly oil/air ,hopefully it is a simple fix, as other than that it seems to be a really good product.

Strength:

What a dropper can do for your riding is undeniable. But for this particular product, there isn't a lot going for it...my experience w/ everything from the product itself, mfg support, and the vendor has left a teaspoon of kitty-litter taste in my mouth.

Weakness:

I'm suspecting there are two crews who make these things...one crew w/ experience w/ mfg tolerances to engineering specs, and another that treats things with, "close enough" attitude. By close enough, I'm referring to the response of mfg support's (Rick Taylor) to my 1/16" vertical play and the associated "clunk" as seal seat-in, or the play of the seal w/in its carriage to cause play. Rick, in any other industry this is called not meeting tolerances.

The 1/16" vertical play was notice on first install and after a car park test ride. Upon this discovery, the post was removed to make sure everything was secure and nothing was loose out of the box. I found tool marks on the base spanner plate and nut. I immediately contacted OutsideOutfitters for a RMA, citing the play and the tool marks. No response for two days...so I called. They refuse to issue a RMA citing they don't take returns of, "used or installed parts." I don't know if it's too much to expect a 100% working part out of the box, but am I expected to perform a full product test prior to installing the post?

So, despite OutsideOutfitters having one of the best prices on the 'Net for bike parts, I will not buy from them in the future...purely because of their unreasonable return policy.

Upon the DENIAL of return by OutsideOutfitters, I sent ($13.30 USPS) to post back to KS support (Rick). Keep in mind this post has not seen dirt yet. KS replaced the cartridge and claimed they tested the post and it was 100% repaired. When I received it, I did do a test for the play and lo' and behold, NOT FIXED. Tried contacting OutsideOutfitters again to the same results...no returns on installed/used items. After some discussion w/ Rick at KS, I asked if he could replace the parts that need to be swapped w/ bits from an older production run as my riding buddy's older i950 has absolutely NO play. Another $13.30 and off to KS again, still a dirt virgin. When returned, STILL NOT FIXED, followed by a comment by Rick of, "seal seat-in." I finally took the post out for a ride to see if I can live w/ the clunk...and no. Every time the post is unloaded, then loaded w/ my weight (187.5lbs), there's an audible and tactile "clunk".

So at this point, I have filed a charge dispute on a defective product w/ my credit card company. I would also ADVISE highly AGAINST buying KS PRODUCTS, and ESPECIALLY from OutsideOutfitters.com for their unreasonable return policy. I'm 2 warranty services into this post before its first ride, and it's still no working properly, and the vendor refuses to swap me for another. NICE!

FYI, I'm a former shop mech who builds his own bikes from rims and spokes up.
