💡 What are rear derailleur hanger bolts used for on a bike? These bolts keep the derailleur hanger and chain tensioner firmly attached to the frame so shifting stays precise on every ride. - They replace stripped or lost hardware on many standard bicycle frames without needing adapters. - Proper thread engagement prevents loosening during rough trail or street use. - Lightweight alloy construction adds minimal weight while resisting corrosion. - Always check frame thread pitch before install to avoid cross threading issues.
