FAQ
How do I install or service the S7?
Please follow the step-by-step installation instructions available at the link below:
This guide covers installation, setup, and important safety information. Professional installation is recommended.
How regularly should I service my dropper post?
We recommend you do an upper bushing clean-and-grease every 25hrs of riding, a full clean and grease service every 75-100hrs of riding, and a full rebuild every 250-350hrs of riding.
Are the seat clamps compatible with oval carbon rails?
Yes, our seat clamps are fully compatible with 7x7mm & 7x9mm carbon seat rails.
What grease should I use to service my post?
We recommend using a light suspension grease during service.
Light suspension greases such as Slickoleum or Slick Honey work well. Do not use oils or heavy greases, as they may negatively affect performance.
Does the S7 work with a mobile app?
No. The S7 does not support mobile app connection or app-based control. It is designed to work directly with the included wireless remote, with no app setup required. App connectivity is available on the S8 model.

I was in the market for a dropper on my single speed. Rebuilding on my old fox transfer was my first choice but this post was close to the same price so it was worth trying it out. Glad I did. Packaging is top notch. Easy to link remote and post. After about 400 miles on this post I’ve recharged it twice. When the battery does die you are stuck where it’s at. Not a negative just pointing that out. The only complaint I had was the saddle rail clamp kept coming loose. Drop of blue loctite fixed the issue. Make sure and order the post with an extra battery. Love the post enough I bought another one for my enduro.
Excellent dropper at such a good price point. Delivery was smooth and the actuation is smooth and fast. Thanks for making wireless droppers so affordable!
The dropper feels like a good quality, easy to install, it took literally 10 minutes to install it.
The response is very quick, the Bluetooth is already connected, and the remote is compatible with the Magura mount.
I have a disability that makes getting on and off the bike difficult and on steep downhills I struggled to get behind the seat and came close several times to doing an endo. The frame on my Cannondale Scalpel would not accept a cabled dropper post and wireless ones were out of my price range. Then I heard about the Seekrun S7. At the time there were only three reviews but all were five star. The product looked good and solid and the price was less than a lot of the cable activated dropper posts. I decided to purchase one, contacted the company in Alberta on a Friday morning and had the product in my hands here in Ontario by Monday afternoon! Scanned the code for an instruction manual and found clear instructions on installing and pairing which went very well. It was so easy! Now off to the forest! Getting on the bike is no longer a struggle and steep downhills are much safer. Bonus, I can’t stand up to pedal but being able to raise the seat a little more than the height of my stationary post allows me to put more power into the pedals on the climbing end of things. I am completely happy with the Seekrun dropper post. It is fluid and works flawlessly! It is a well built, solid and very responsive, quality product. Thank you Seekrun for enabling me to tackle some of the more technical trails when I’m out mountain biking! Very happy to give the post another five star rating.
Great product. Great price.
I love the quality, but the dropper comes up very fast . Will there be some adjustability in the future?
Amazing! For the price, the performance is unreal. Cannot recommend the S7 enough to anyone looking into getting themselves a witless dropper.
So far it's great. Snaps back up super quick just how I like it. I haven't found anything to complain about. I'll be ordering another.
Great!
Works awesome battery does not hold a charge very long though. Runs out after or during the ride. Awesome that the only thing from getting 5 stars
Just received my new S7 dropper...i just love it! Good quality, works like a charm and fully reliable. Seekrun for the win! Keep up the good work guys!!!
it is a game changer and make biking possible for seniors.
Love the post, works great! Marginally heavier than the competition, great quality, great price!
Customer service is one of the best I seen so far. After going thru there massaging system I got an answer right away and solution was given.
Just the replacement I got works but still a little slow when it goes up, that is why only 4 stars.
Highly recommended.
Great initial quality. Very impressed! Operates without flaw. Fast up. Easy down. No delay from press of button to post actuation. I’ve ran One Up, e Thirteen, Fox and other brands, and the Seekrun quality is on par with all.
Not the lightest but does exactly what it's supposed to do consistently!
Put the seatpost on my son’s bike. Have only used it in the bike stand and some test rides, but so far it is flawless and so easy to set up
Awesome customer service highly recommend
Great product, easy install. Only drawback is that it is not app supported, although at this price point, that’s a minor setback.
Works great. I purchased a 30.9 diameter so it can use it on all of my bikie frames with shims. The return feels so instant with the pressing of a button compared to the extra time it would take to push in a manuel remote. Also was a nice touch to have a free service kit with the purchase. Only negative is the weight. but you already accept that when you purchase electric.
