## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Good chainring for the price
  

*by B***. on Reviewed in the United States on March 26, 2019*

Installed easily onto my Deore 591 crankset, no issues with chain drop. Anodizing is wearing a little faster than other chainrings I have had, but for the price I think it is great. Used on a 9 speed touring bike I commute on.

### ⭐ 







  
  
    One speed
  

*by T***S on Reviewed in the United States on December 12, 2019*

This sprocket will only fit a one speed. I have an 8 speed shimano w narrow chain and the sprocket would not mesh(new chain). I took the sprocket to my one speed and it fit perfect.

### ⭐ 







  
  
    Not working on all bikes
  

*by J***E on Reviewed in the United States on October 9, 2019*

This does not work on my bmxrace bike, sproket fit on fine and was 44 t like i ordered, but the teeth are too thin , this is only for a 1/8in chain dont buy if you have a thick chain
