## Customer Reviews

### ⭐⭐ 







  
  
    Not sure how this is supposed to work, Instructions or derailleur compatibility would be helpful
  

*by A***A on Reviewed in the United States on October 2, 2018*

It's a shim that varies in thickness as it goes around the tube so it doesn't allow for entire surface of derailleur clamp to make contact with the tube. It didn't work with my Shimano SLX front derailleur. Maybe it will work with yours?

### ⭐⭐⭐⭐⭐ 







  
  
    Worked perfect!
  

*by G***N on Reviewed in the United States on June 10, 2018*

Worked perfectly to shim a Shimano front derailleur to 31.8 mm. Thanks!

### ⭐⭐⭐⭐⭐
