absoluteBLACK absoluteBLACK HOLLOWcage Oversized Derailleur Pulley Cage - For SRAM AXS, Full Ceramic Bearings, Carbon Cage, PVD Rainbow

The absoluteBLACK's HOLLOWcage® for SRAM eTap AXS RED and Force 12-speed derailleurs makes the AXS drivetrain whisper quiet. It features a carbon-polymer mono-plate construction with bespoke, oversized, full ceramic bearings and one of the most advanced silencing pulleys ever made.

- Designed for use with SRAM RED and Force AXS drivetrains
- The Silent Xring Pulley dampens the chain impact on the guide pulley teeth, eliminating the engagement noise
- Incredibly silent (over 12dB noise reduction vs stock)
- HOLLOWcage uses full ceramic bearings (Silicon Nitride ceramic balls and Zirconia Oxide ceramic races) that make the guide pulleys incredibly stiff for greater shifting precision
- One of the lightest oversized cages on the market (69g)
- Works with 10-28t, 10-33t, and 10-36t cassettes
- Not compatible with SRAM XPLR or 11-speed RED/Force
- ONLY works with AXS flat top chain
