From seated climbing to jockeying technical sections, the Crux-I offers a 100mm range of height lock, permitting riders to adapt to an array of conditions. The 1-bolt micro adjustable seat rail clamp ensures a secure clamp even when the trail takes a turn for the rowdy.

  • Aluminum construction with adjustable air preload, 100mm range of height lock
  • 1-bolt micro-adjustable seat rail clamp, zero offset head

First dropper and good if you're on a budget!
Bought this post when Jenson had their huge Memorial Day sale. So far so good. Comes up at a moderate speed and easy to put down. Taken it on a few rides and I'm very impressed with it

My first dropper seat post
This seat post is a very nice addition to my mountain bike. Great price (on sale) and easy to install on my Kona Cadabra. I haven't had it very long but so far so good.
I really love being able to drop the seat when stopping (to get both feet on the ground) and when going down a hilly trail.

Bang for the buck.
Good item. You get your money's worth. Although the seatpost rises slowly & doesn't extend all the way up until it's broken in.

Great post for the price!
I wanted a dropper post on my hardtail, but didn't want to spend a fortune. It was easy to install and works well. It does have a smidge of play laterally, but thankfully it is not noticeable while riding, only when you twist the seat left to right(unlike my RockShox Reverb I had to send away for warranty). It is only 100mm travel which means I have to run it a bit higher than I'd like, but for the price it does the job. The return is slow compared to other more expensive models and it is heavy by comparison as well. I also wish they had included an air valve to adjust the pressure rather than having a preset cartridge, but I guess all these things are in the name of getting a reliable post for cheap. I highly recommend this post if you are on a budget.

Never popped up, maybe that's why they call it dropper?
It didn't work from the moment it was installed. Either too much stichtion or not enough pressure to pop it up. I'm returning it. JensonUSA is taking it back. You guys rock!

Returned this one
Installation was simple enough, but the cartridge did not return seat to full height. Tinkered with it to try to get the seat to return fully, and while I was moving the lever on the handlebar, the clamp, which was made of light plastic, broke. I understand the cartridges occasionally failing and assume that would have been warrantied no problem. But the fragile handlebar clamp was a no-go. I went with another model instead, one that uses a sturdier clamp, but also cost $150 more than I paid for this KS.

What's the distance from the seat collar to the seat rails with the post fully inserted into the frame and extended? In other words, with the post at full extension, how low could I get my seat?
Miki V on Feb 24, 2017
BEST ANSWER: With post fully extended the min height from the centre of your seat rails to bottom of the seal collar/top of seat post clamp is approx. 170mm
hi what it include in the box

BEST ANSWER: Post, remote switch, cable and assorted mounting bits. Basically everything you need!
What's the difference between this and the eten? Looking for a 27.2 dropper for my wife's bike without breaking the bank.

BEST ANSWER: Internal cable routing The cable comes out of the bottom of the seat post rather than right under the seat but you can shoehorn the cable through the lower screwhole for the water bottle mount on the seat tube if your bike does not have internal cable routing features
I'm thinking about buying this post but my current seatpost is cut and since I'm kinda short I was wondering if there is a way to cut a dropper seat post? Cheers
Spears on May 28, 2017
BEST ANSWER: No! Absolutely not! Never, ever modify a dropper seatpost.
Can I set the travel anywhere within the 100 mm travel? Let's say if I just want to drop it half way the travel, can it be done with this dropper post? Thanks!
