### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Shift replacement
  

*by L***F on Reviewed in the United States on August 24, 2024*

I like the fact instead of twisting the grip on the old shifter was hard due to arthritis in my wrists. I installed these new shifters and they work great .Yes I recommend this

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Simple to install.
  

*by W***Y on Reviewed in the United States on May 15, 2024*

got them installed on an old bike and it shift's great. sis works perfectly with changing the gears. really revived this bike. dials indicator pieces on top a little are a little plasticy and not very sturdy they wobble back and forth as you tap them. I assume they're just snapped in pieces and they're going to be fine. but I had to have a gripe for 4 stars and not 5.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars
