SRAM Universal Derailleur Hanger is engineered to simplify bike compatibility while improving drivetrain reliability across modern mountain bikes. Designed as a single standard to replace thousands of hanger variations, it helps riders and mechanics reduce guesswork and downtime. The hanger is built to rotate backward during impacts, protecting the derailleur and frame from damage when strikes occur. Its ability to self align and help guide the chain back toward proper position improves overall shifting consistency | SRAM Universal Derailleur Hanger (UDH)
