Absolute Black Carbon-Ceramic HOLLOWcage
HOLLOWcage for Shimano 9100 / 8000. The revolutionary mono-plate design is the quietest, best shifting, aerodynamic derailleur cage design created to date.
It is a dawn of new era for rear derailleurs. HOLLOWcage has a carbon-polymer mono-plate construction with bespoke, oversized, full ceramic bearings and the most advanced silencing pulleys ever created.
- 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, which is the single biggest contributor to overall drivetrain noise (over 12dB noise reduction vs stock)
- The shifting is as good as with the original Dura Ace cage. Abnormally large, bespoke, 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 (and therefore lower pulley) to align better with the angle of the chain when using the higher gears of the cassette. This means less friction (and less watts 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 (and lowest watts lost) for your needs
- Compatible with Shimano Dura Ace 9100 / 9150 / 9170, Ultegra 8000 / 8050. Fits up to 32T cassette
- Size (Mass +/-1g): 71g
- Compatibility: Shimano Dura Ace 9100 / 9150 / 9170 , Ultegra 8000 / 8050. Fits up to 32T Cassette
- Materials: Carbon Fiber-Polymer Matrix, 7075 Aluminum, Rubber, Ceramics
- In the Box: Complete Cage, Lockring Tool, 2x Spare XRing Rubbers, 14ml GRAPHEN-lube
WHY IS THE HOLLOWCAGE SO SPECIAL?
* It's super silent (over 12dB noise reduction vs stock)
* The shifting is as good as with the original Dura Ace cage
* It’s more aero than the OEM cage and other oversized cages
* It saves more watts than other cages
* One of the lightest oversized cages on the market
* First mono-plate construction of its kind
Absolute Black is introducing a completely new generation of pulleys, with the ability to reduce the sound level by 12-14dB when compared to stock Dura Ace pulleys. This corresponds to roughly 60% of the noise reduction. Practically speaking, the cage becomes super silent.
Absolute Black uses a patent pending solution, their all new special xring rubber suspended bands designed to dampen the chain impact on the guide pulley teeth, thus eliminating the engagement noise, which is the single biggest contributor to overall drivetrain noise. From now on, your ride is going to be quieter than ever before, allowing you to hear things you weren't able to notice before. It's the new era of derailleur cages!
