Works as advertised. This is by far the least expensive but equally effective wireless dropper post on the market today.
Great post works awesome!
Love my S8 dropper post. Very easy to install. Even easier to use. Very fast and functional!
Awesome dropper filled with fantastic features thru a pretty good app. The height control feature is shockingly good and a pleasant surprise.
Remote functionality is fabulous and handlebar placement is infinitely robust.
Waiting for the gold 200mm so I can buy. Works same if not better than Fox's or Rocksuck's eDroppers at a fraction of the price...a no brainer purchase.
Fantastic customer service. Some issues with the first one but they rectified the issue right away.
Great product and excellent customer service. I have a heavy ebike and this allows me to get on and raise to my comfortable level !
The operating manual is a bit lean but once all system are operational, it is a great product for the price.
Nice quality and works great. Good service and communication with seekrun Canada.
