*by C***N on Reviewed in the United States 🇺🇸 on October 2, 2019*

this is a inexpensive alternative for a dropper upgrade. its all mechanical so you have only three positions. i put it on an older bike that i didnt want to spend much money on.

### ⭐ 1.0 out of 5 stars







  
  
    Worked good for a short time, but DROPS randomly.
  

*by I***N on Reviewed in the United States 🇺🇸 on June 17, 2019*

My initial review of this was 4 stars because it appeared to be well built and was relatively inexpensive.However after only a few rides, the post started randomly and abruptly DROPPING during riding.  This happend without warning every few minutes and is a violent drop... enough to almost cause a wreck.I tried adjusting the cable, the lever, lubing the internal release mechanism, but it simply didn't hold in the high position dependably.  It got worse as time passed. It got to the point where during my entire ride, I was just waiting for it to randomly drop over and over instead of enjoying the ride. I discovered this after the return period, so it went in the trash.  Was just too dangerous for me to use.
