## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Does what narrow-wides are supposed to do; nice price.
  

*by J***N on Reviewed in the United States on December 30, 2017*

Got this for my 10-speed (1 x 10). The narrow-wide design assures that the chain stays put without a guide or front derailleur.
