    It Works
  

*by M***V on Reviewed in the United States 🇺🇸 on September 26, 2020*

I used too much pressure when biking which grinded down part of my crank arm thread that connects to the screw. The bike repair shop tried to charge me $80 to fix this but I just bought this new crank arm and new bolts for like $20 total and installed it myself. Super easy and works fine still.
