The E-Ten is Kind Shock's newest height adjustable dropper post. It's their most affordable dropper seatpost but has features and functionality you'd expect to see on more expensive models.
Kind Shock recomends applying a thin layer of friction paste before you insert the post in your frame. It's the stuff used on clamped carbon fiber parts. Finish Line Fiber Grip is one of the best on the market.
I've been using this for a few months now. It was my first dropper, and won't be my last. It really does my riding even more fun! Works very well for the money, but lacks saddle adjustment. I'll probably upgrade to one with a two bolt head later this year. Cable setup can be a tad tricky, but really not to bad.
I bought this post for my 2012 Jekyll 4 a year and a half ago and it has been great! I was a little worried about performance because of the price, but I have been totally happy. I love that you aren't limited to only 3 positions. You can stop it at any point and it holds. I've been so pleased that I recently purchased another E-Ten for my other bike. No major issues to this point. I would highly recommend it.
I've been using this E-Ten dropper for a year and have had a few issues. Still goes up and down like it should so the internals are awesome. Cable actuator has had some issues along the way. The cable housing can slip out of the barrel adjuster causing the seat to drop. Used some electrical tape to keep housing in place. The plastic switch would stick and no amount of oil or maintenance would get it to work correctly. Because it's a value priced post the switch is all plastic. I was able to locate a used KS anodized switch from LBS to solve the problem.
A friend had this post and the 300$ ks (not sure which model). He said his eten performed as well as the more expensive, and highly recommended it. After several rides i feel comfortable saying this post is well worth the price and performs, well, i suppose as a dropper post should. Zero issues so far. I recommend it to anyone in the market, and i think it's a great safety feature to add to a bike, especially if your favorite trails vary greatly in type and terrain. In short, even if i wanted to spend $300+ on a post, i see no reason to not simply buy 2 etens.
Yes, it's not the top of the line and other posts available are likely better, but they are also twice the price. For the money, you would be hard pressed to find a better post. I've had mine for 8 months and I've been thoroughly impressed with the quality and performance. I've only had two minor issues with it. When I first installed the post it kept slipping in the seat tube. A little anti-seize and slightly tighter clamp pressure, problem solved. The other was in sub 20 degree weather the lever at the top of the post froze open creating a pogo post. Used my hands to warm the lever area and after a few minutes it returned to closed position. Just kept the post fully extended the rest of the ride. Even with the the minor issues I'm extremely happy with this purchase. I would absolutely purchase it again.
I am very happy with this post. The finish is not that of the LEV or other high end offerings, but it is still above what you would expect for a product this reasonably priced. The plastic remote is the same same as the more expensive metal models, and with gloves on, it doesn't bother me that it's plastic. Setup was a breeze. The return rate was way too slow at first, but once I figured out that it was just a little too slack in the cable, it was a very simple fix. KS is really leading the way in the dropper post market. They offer both the best and best value post available.
For $150.00 I figured I would give it a try as I was not bend towards paying $300.00 plus for a known brand dropper post. Have to admit I was skeptical, but it worked like a charm! Easy to install and sturdy, and the handlebar level is very easy to use. Just push and it will drop, push again and it will rise softly and it will accept your desired post height at the time. No play or swivel felt at the saddle, remained firm and precise. I 'ld reccomend it. If it stays working as good, it will be the market choice.
After playing with friends' bikes that have droppers, Ive been wanting a drop post for a while now. Only problem, is I did not want to deal with the reliability issues that plague a majority of the brands on the market, and on the other hand did not want to spend $350+ for one of the models known to be more reliable. When I heard about the eTen, I thought at that price, there is no way it could be any good...till I started reading the testimonials from people who had them. I had to try one. So now, after 50 miles in pretty dusty conditions, I couldn't be happier! The post is just as smooth as my buddies RS post (has been rebuilt twice in 1.5 years), but the trigger is way more user friendly. Its also way smoother than my other friends Krono, (currently on its way back to KB for the second time). Installation was simple, I had mine installed on my 2012 Fuel EX8 in less than 30 minutes. One thing to keep in mind that should be mentioned in the product description is; the manual wants you to apply friction paste (used for carbon fiber parts) to the outer shaft, and use a standard non-QR seat clamp torqued to 7nm...I had neither of those things on hand, so I had to borrow a clamp and paste from a buddy to get the install complete. I would have bought them both when I ordered the post had I known. Other than that minor hiccup, I am stoked with the product. For the price, Im tempted to pick up another eTen so that I will have one to ride if I have a problem with my current post!
