Absolute Black Derailleurs & Parts|Hollowcage Carbon Ceramic Oversized Derailleur Pulley (Black) (Shimano 9100/8000)

• HollowCage has a carbon-polymer mono-plate construction with bespoke, oversized, full ceramic bearings and advanced silencing pulleys
• Special xring rubber suspended bands dampen the chain impact on the guide pulley teeth, therefore eliminating the engagement noise
• Full ceramic bearings make the pulleys incredibly stiff and very tall teeth of the upper pulley gives the best possible shifting precision
• The mono plate cage can dynamically adapt to the chain angle as it allows the cage to align better with the angle of the chain when using the higher gears of the cassette
• Less friction lost as the pulley doesn’t have to fight against the chain itself
• Adjustable spring tension lets you adjust for cassette size and chain length to find the lowest possible tension for your needs
• Compatible with Shimano Dura Ace 9100/9150/9170, Ultegra 8000/8050
• Includes: Complete cage w/ pulley wheels, lockring tool, 2x spare xring rubbers, 14ml lube
