### ⭐ 







  
  
    After installed it slip by not working i would not recommending and it not shimino it shimming.
  

*by T***I on Reviewed in India on 7 June 2021*

My left hand side shifter, which is of front derailleur doesn't shift on and It slips by and this is happening after installing on my bicycle because of the tightening of string but if i uninstall it seems to be fine, then it gives clicking sound as i press the button.

### ⭐⭐ 







  
  
    The product is not of the brand they say it is.
  

*by R***L on Reviewed in India on 28 January 2021*

This product says Shimano, but i was delivered with a "Shiming" company product. It's pretty much like those branded items' rip-offs.
