HOLLOWcage® V2 for eTap AXS Red & Force 12spd derailleursfinally makes your AXS drivetrain whisper quiet.Our revolutionary mono-plate oversized pulley wheel (in short OSPW) is the quietest and best shifting oversized derailleur cage for eTap AXS created to date. HOLLOWcage ® OSPW has a carbon-polymer mono-plate construction with bespoke, oversized, full ceramic bearings and the most advanced silencing pulleys ever made. Sram eTap AXS is known to be louder than other drivetrains. Our HOLLOWcage® with Silent " Xring Pulley™ " completely eliminates this problem allowing you to enjoy the ride.
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.
