AbsoluteBlack Hollowcage V2 Carbon Ceramic Oversized Derailleur Pulley Cage - SRAM AXS (Red/Force)

The AbsoluteBlack Hollowcage V2 Carbon Ceramic Oversized Derailleur Pulley Cage replaces the stock pulley cage on a SRAM AXS Red or Force derailleur with a larger 12-tooth upper and 18-tooth lower pulley setup, built on a mono-plate carbon-polymer matrix reinforced with 7075 aluminum. The oversized pulleys route the chain in a straighter path through the derailleur, and the whole cage comes in at just 65 grams, using the same carbon material SRAM uses on its own RED eTap AXS derailleur cage.

The bearings are where the real engineering sits: full ceramic units with Zirconia Oxide races and Silicon Nitride balls, independently certified through X-ray diffraction testing. Paired with AbsoluteBlack's X-ring Pulley design — which uses suspended rubber bands inside the pulley to absorb chain impact — the cage runs measurably quieter than stock, rated at an 11dB reduction, or roughly 70% less noise than SRAM's standard AXS pulleys. The carbon components are injection-molded with the carbon fibers optimally aligned for strength, and the glossy finish shows off the weave rather than hiding it.

This cage is built specifically for SRAM eTap AXS Red D1/E1 (2022 and newer), Force D1, and Rival D1 12-speed derailleurs, running an SRAM AXS Flat Top chain across 10-26T, 10-28T, 10-33T, or 10-36T cassettes — it isn't compatible with SRAM XPLR, Force E1, or Rival E1 setups, so it's worth confirming your derailleur generation before ordering. It's available with a black, titanium, red, gold, or PVD Rainbow lower lockring for riders who want the upgrade to show. At $469, the Hollowcage V2 sits at the premium end of drivetrain upgrades — a purchase for someone chasing lower friction and a quieter drivetrain on a bike that already runs SRAM's top-tier AXS groupsets.
