HOLLOWcage® V2 for Shimano 9100 / 8000. Our revolutionary mono-plate oversized pulley wheel (in short OSPW) design is the quietest, best shifting, aerodynamic derailleur cage design created to date. It is a dawn of new era for rear derailleurs. HOLLOWcage ® OSPW has a carbon-polymer mono-plate construction with bespoke, oversized, full ceramic bearings and the most advanced silencing pulleys ever created.
What’s new with V2
We devoted countless hours to sourcing advanced materials, all while refining the very essence of the mono-plate construction. The new mono-plate also boasts a glossy finish that highlights the carbon fiber construction. It is now made from the very same material as used by SRAM in the RED eTap AXS derailleur cage. Our ceramic bearings have been rigorously tested and independently certified using X-ray diffraction by Lucideon Ltd, a UKAS-accredited authority in ceramics and material science.
