HOLLOWcage® for eTap AXS Red & Force 12spd derailleurs finally makes your AXS drivetrain whisper quiet. Our revolutionary mono-plate 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.
FIND CORRECT CHAIN LENGTH FOR HOLLOWCAGE SRAM AXS
Wrap the chain around the biggest sprocket of the cassette and the biggest front chainring, omitting completely the derailleur cage. Holding the chain under tension, pull the ends together so they touch. This is the base length.
Depending on the drivetrain you need to add the following to the base length:
- Extra two links for 10-28T & 10-33T cassette in 2X scenario.
- Extra two links for 10-36T cassette in 2X scenario.
- Extra four links for 10-33 or 10-36T cassette in 1X scenario.
- Extra four links in 2X scenario only if you are upgrading from 10-33 to 10-36T cassette (ie. when your bike came with 10-33T but you upgrade to 10-36T).
WHY IS OUR HOLLOWCAGE® SO SPECIAL:
- It is super silent (over 12dB noise reduction vs stock).
- The shifting is as good as with the original Dura Ace cage.
- It's more aero than the OEM cage and other oversized cages.
- It saves more watts than other cages
- One of the lightest oversized cages on the market.
- First mono plate construction of its kind.
