Bring crisp, quiet, reliable shifting back to your 12-speed Eagle drivetrain. This genuine SRAM X01 Eagle service kit replaces the two worn jockey wheels and the inner cage in one go, so your rear derailleur tracks the chain accurately again instead of skipping, ghost-shifting or rattling.

Highlights

  • Complete pulley-and-cage rebuild kit in a red finish to match X01 Eagle
  • 12-tooth upper (guide) pulley and 14-tooth lower pulley
  • X-SYNC tooth profile for confident chain retention and smooth running
  • Forged aluminium inner cage plate with three mounting bolts included
  • Fits 12-speed SRAM Eagle rear derailleurs

Why replace pulleys and cage together

Jockey wheels wear faster than almost any other drivetrain part, and a tired inner cage adds play that throws out shift alignment. Renewing both at once restores the correct geometry and a like-new shift feel, rather than chasing problems one component at a time.

X-SYNC pulleys

The pulleys use SRAM's X-SYNC tooth profile, with a tall, square tooth shape that meshes precisely with 12-speed Eagle chains. The result is better chain control through rough terrain and quieter, more efficient pedalling.

Compatibility and fit

Designed as the service kit for SRAM X01 Eagle 12-speed rear derailleurs, and also suited to other 12-speed Eagle mechanical derailleurs including XX1 and GX Eagle. The lower pulley is larger than the upper pulley and must be fitted in the correct position. This is a mechanical drivetrain spare, not an AXS/electronic part. If you are unsure whether it suits your exact derailleur, contact us before ordering.

SRAM components are covered by SRAM's manufacturer warranty against defects in materials and workmanship. This warranty does not cover wear from normal use (jockey wheels and cages are wear items), improper installation, or damage from crashes or misuse.

If you believe your item is faulty, please return it to Tune Cycles and our team will assess it and arrange support on your behalf. Do not contact the brand or distributor directly.
