Absolute Black Sram AXS derailleur cage

Absolute Black Hollowcage cage for Sram Etap AXS 12 speed derailleur

The Absolute Black Hollowcage Sram eTap AXS 12-speed cage finally makes your AXS drivetrain quiet. The revolutionary OSPW Single Plate is the quietest, highest performing oversized derailleur cage for eTap AXS created to date. Hollowcage OSPW has a single-plate carbon polymer construction with oversized, custom-made all-ceramic bearings and the most advanced quiet pulleys ever made. Sram eTap AXS is known to be noisier than other drivetrains. Our Hollowcage with Silent “Xring Pulley™” completely eliminates this problem allowing you to enjoy the ride.

Strong points :

• High-end ceramic pebbles
• Oversized derailleur cage
• OSPW in ultralight carbon (only 75 grams)
• Aerodynamic golf ball texture
• Quietest screed in the world

Features :

• Hollowcage has a single-plate carbon polymer construction with custom oversized full-ceramic bearings and muffler pulleys.
• Special xring rubber slings cushion the impact of the chain on the tensioner teeth, eliminating engagement noise.
• The single disc cage can dynamically adapt to the chain angle, allowing the cage (and therefore the lower pulley) to better align.
• Adjustable spring tension allows you to adjust cassette size and chain length to find the lowest possible tension.
• Box includes: Complete cage, lock ring tool, 2 spare ring rubbers.
• Compatible with SRAM AXS Force and Red
• Verified weight: 75 grams

Advantages of the Hollowcage OSPW screed:

• Ultra-quiet operation (over 12 dB noise reduction compared to original systems)
• Improved aerodynamics compared to stock treads and oversize treads
• Significant energy savings compared to original systems
• One of the lightest screeds/rollers on the market
• Shifts as precise and fast as original
• First single screed type system
• New era of silent transmission thanks to XRING rollers

Polymer pulleys offer significant noise reduction compared to aluminum models, thanks to patented XRING rubber technology that dampens chain shock, eliminating unwanted noise.

The flexibility of the OSPW clevis improves efficiency, allowing the bottom roller to better align when using the cassette's high speeds. This reduces friction, thereby optimizing performance.

The Hollowcage clevis offers a stiffer upper guide roller for more precise transmission, based on ultra-rigid oversized ceramic bearings.

The higher tooth profile of the Hollowcage clevis ensures optimal guidance and increased precision when changing gears.

Contrary to popular belief, the oversized Hollowcage is more aerodynamic, as demonstrated by specific tests carried out in a wind tunnel.

Restitution of Watts:

Four main components minimize power loss, with oversized ceramic bearings, optimized tooth count, adjusted clevis tension spring, and lower components dynamically aligned with chain angle.

The Hollowcage clevis requires a spring setting at the lowest setting for optimal installation, providing high quality and precision gear changes. The instructional video guides installation, and the 4-year bearing warranty ensures product durability.
