SRAM 12 Speed XO1 Eagle Rear Derailleur

SRAM 12 speed XO1 Derailleur has been specifically engineered to accommodate the Eagle drivetrains need for greater capacity, including the brand new 10-52T Eagle cassettes, while still being compatible with older 10-50T cassettes.
  • X-Horizon design offers slick shifting
  • Type-3 roller bearing clutch provides excellent chain retention
  • Re-engineered mounting system and cage lock
  • Designed to be used with SRAM Eagle drivetrains 
  • Suitable for new Extended Range 10-52T Eagle cassettes


The Eagle Derailleur features a 14-tooth X-SYNC lower pulley to allow for the 10-52T Extended Range cassette, a type-3 roller bearing clutch for maximum drivetrain stability with reduced derailleur bounce and chain slap, a re-engineered mounting system and a re-positioned cage lock system for easy chain and wheel installation and increased durability. Designed to be used with SRAM Eagle drivetrains and Extended Range cassettes, the X01 is a fundamental component in the Eagle range.
