### ⭐⭐⭐⭐ 







  
  
    Just what I needed
  

*by N***4 on Reviewed in the United States on September 28, 2016*

Works as described...perfect fit

### ⭐⭐⭐⭐⭐ 







  
  
    Enables my dropper seatpost installation
  

*by B***Y on Reviewed in the United States on June 22, 2016*

I wanted to install a Gravity Dropper Classic seatpost, which was designed for a 27.2 seatpost tube. However, my Yeti ASR 5 26" MTB's aluminum frame has a seatpost tube with an larger I.D. than that.The 27.2mm dimension is typical of most dropper seatpost models from various manufacturers.Precisely machined. Nice finish on it. Works well.

### ⭐ 







  
  
    Dimensions are off...
  

*by A***  on Reviewed in the United States on October 10, 2017*

Did not fit, dimensions are off, it got stuck half way in and I had to damage it to get it out...I had to cancel my return because of the damage. I bought a 30.9 seat post at a much higher cost and it did fit perfectly.27.2 to 30,9 shim is not accurate so beware. You could try a smaller size than you think you need but then it’s a guess!
