It is the dawn of a new era for rear derailleurs.

The revolutionary monocoque design of Absolute Black is the aerodynamic derailleur cage design, with better shifting and quieter operation created to date.

• HOLLOWcage has a monocoque construction of carbon polymer with custom-made large ceramic bearings and silencing pulleys.

• The special suspended xring rubber bands dampen the impact of the chain on the teeth of the guide pulley, thus eliminating coupling noise.

• The monodisc cage can dynamically adapt to the chain angle, as it allows the cage (and thus the lower pulley) to align better.

• The adjustable spring tension allows you to adjust the cassette size and chain length to find the lowest possible tension.

• The box includes: complete cage, lock ring tool, 2 spare x ring rubbers.

• Compatible with SRAM AXS Force and Red
