    Dangerous, weak metal, could have been seriously injured
  

*by G***C on Reviewed in the United States on December 21, 2019*

Dangerous...broke on my third ride. Weak metal, snapped right off on a section of singletrack and I almost went right off the trail.

### ⭐ 







  
  
    snapped at bolt
  

*by E***E on Reviewed in the United States on March 7, 2020*

I bought this in Sep 2019.  I finally got around to adding it to my build.  I have under 10 hours on it.  It snapped while I was riding.  Thanks to quick reflexes I was not hurt.  This is junk.  Protect & preserve the south entrance to the alimentary canal.  Do not trust this seat post!

### ⭐⭐⭐⭐⭐ 







  
  
    Accurately sized, and has a really useful feature in the seat clamp.
  

*by R***T on Reviewed in the United States on January 26, 2020*

Most seat clamps are a minor pain in the neck; with the upper parts loose enough to slip the seat rails into place, the bits flop around so much that you almost need a third hand to hold it all in position while snugging down the bolt.  This clam adds a spring that keeps tension on the bolt for you, allowing easy assembly every time.  Amd the tubing is beefy enough to produce no worries about strength.
