Show Description

Brace yourself, the budget Eagle has landed. An evolution of the proven 1x specific X-HORIZON line, this derailleur suits enduro and trail riders ready for the 12-speed world. You don't have to compromise gear range, weight or reliability. The large 14-tooth lower pulley allows 10- to 50-tooth cassette capacity in a relatively compact design, and offers a smooth pedalling feel. The roller bearing clutch features a smoothed torque curve for quiet, consistent operation, And the cage lock is moved back, out of the way to protect it from trail debris.

  • Compatible only with SRAM Eagle 1x12 drivetrains.
  • Roller bearing clutch minimizes chain-slap and derailleur bounce.
  • Cage lock keeps derailleur cage in place for easy wheel removal and maintenance.
  • Offset X-SYNC pulleys yield solid chain engagements, durability and reduced chain gap.
  • X-HORIZON design eliminates ghost shifting.
  • New pulleys are efficient, crisp and quiet.
  • Aluminum cage and lightweight hardware.
