## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Longer would be better not ideal for dropper post shim
  

*by A***R on Reviewed in the United States on August 17, 2019*

The shim diameters are perfect but the overall length could be longer to provide support for the full length of the seatpost. Using it to fit a dropper post in my frame but i had to make my own shim to support the bottom of the post.
