Introducing the AbsoluteBlack Hollowcage derailleur hanger for Shimano Ultegra / Dura Ace.

Our revolutionary OSPW single-disc design is the quietest, most efficient and most aerodynamic derailleur hanger ever created. It's the dawn of a new era for rear derailleurs. The HOLLOWcage ® OSPW derailleur clevis has a carbon-polymer single-plate construction with oversized ceramic bearings and the quietest pulleys ever created.

WHY IS HOLLOWCAGE SO SPECIAL?

Super-quiet: over 12 dB less noise than the original Dura-Ace clevis, a reduction of around 60%.
Gear shifting is just as good as with the original Dura Ace. HOLLOWcage® uses very high teeth on the top pulley, giving the best possible shifting precision.
It is more aerodynamic than the original clevis and other oversized cages.
It saves more watts than other clevises.
One of the lightest oversize clevises on the market.
The first single-plate construction of its kind.
Special xring rubber slings dampen the impact of the chain on the tensioner teeth, eliminating engagement noise.
HOLLOWcage, unlike other pulley cage systems, uses all-ceramic, custom-made, abnormally large bearings that make the pulleys incredibly rigid. The lower bearing alone is actually large enough to hold an 11D pulley.
The bearing rings are made from 100% zirconium oxide ceramic, and the balls from silicon nitride ceramic. The cage and seals are of course made of low-friction polymer.
Adjustable spring tension lets you adjust cassette size and chain length to find the lowest possible tension.

HOW TO MOUNT THE HOLLOWCAGE:

You should mount the clevis with the lowest spring tension setting (first hole from the left). If you're using an 11-32T cassette in combination with 52/36T or larger chainrings, you may need to mount the clevis with a medium spring tension setting (middle hole) to allow for chain growth, but only if the first position produces a loose chain in the smallest ratio.
Bearings come with a 4-year warranty.
