HOLLOWcage® for Shimano 9100 / 8000. Our 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.

  • 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

Installation
Please refer to the video instruction below.  You should mount the cage with the lowest spring tension setting (First hole from left). If you use 11-32T cassette in combination with 52/36T chainrings or bigger you may need to set the cage with middle spring tension setting (middle hole) to account for the chain growth, but only if first position produces loose chain in small - small gear.
