⚙️ Shimano Dura-Ace Compatibility

The HOLLOWcage V2 is designed exclusively for Shimano Dura-Ace 9200 and 9250 12-speed rear derailleurs.

Compatibility should therefore be checked before installation to ensure the rear derailleur matches the specified configuration.

🛞 12/18T OSPW System

The HOLLOWcage V2 uses an OSPW (Oversized Pulley Wheel) system with enlarged pulley wheels.

The configuration features a 12-tooth upper pulley and an 18-tooth lower pulley.

🪶 Carbon-Polymer Mono-Plate Construction

The cage is made using a carbon-polymer matrix and features a mono-plate construction.

absoluteBLACK uses an injection-moulding process that allows the carbon fibres to be oriented during production and enables the creation of complex cage shapes.

⚙️ Full Ceramic Bearings

The pulley wheels feature full ceramic bearings, with both the races and balls made from ceramic materials.

absoluteBLACK specifies zirconia oxide ceramic races and silicon nitride ceramic balls, combined with polymer cages and seals.

🔇 Xring Pulley System

The HOLLOWcage V2 incorporates the Xring Pulley system, developed by absoluteBLACK to reduce the noise generated when the chain engages with the pulley teeth.

The suspended rubber rings help absorb the impact of the chain against the pulley teeth during drivetrain operation.

🚴 Compatibility up to 34T

The absoluteBLACK HOLLOWcage V2 is compatible with cassettes featuring a largest sprocket of up to 34 teeth.

Correct installation and appropriate chain length are important for proper operation of the system.

📦 What's Included

The package includes the complete HOLLOWcage and the dedicated lockring tool.
