The absoluteBLACK's HOLLOWcage® for Shimano Ultegra 8150 12-speed derailleurs makes the 8150 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 Shimano Ultegra 8150 drivetrains
✓ Fits up to a 34t cassette
✓ The Silent Xring Pulley dampens the chain impact on the guide pulley teeth, eliminating the engagement noise
✓ Incredibly silent (over 5-7dB 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 (71g)
