$200.00$984.00

SKU: N/A Category: Tags: , ,

Improved for October 2024 with faster shift speeds across the gear range! (Note that photos show earlier version of the cage).

Increase chainwrap on your SRAM Red/Force AXS eTap 12-speed rear derailleur to use 2X chainrings and 1X cassettes! This derailleur cage upgrade allows for the widest range of gearing with wireless shifting. Typical installations use SRAM AXS Flattop 48/35, 46/33, or 43/30 chainrings and 10-44 SRAM XPLR 12-speed cassettes. This cage also allows for Shimano 10-45 12-speed cassettes with non-flattop chains and chainrings -- typically 50/34, 48/32, or 46/30. We recommend adding a WolfTooth Roadlink when using a road AXS eTap rear derailleur with 40-45t large cogs.

This cage is optimized for the following rear derailleurs:

  • SRAM Force D1 and D2 eTap AXS Rear Derailleur medium cage (36T max)
  • SRAM Red D1 eTap AXS Rear Derailleur medium cage (36T max)
  • SRAM Red E1 AXS Rear Derailleur (36T max)
  • SRAM Red A2 eTap Rear Derailleur 11-speed (made after June 2020, 00.7518.141.000)

The cage will fit the following rear derailleurs with slightly slower shifting than the optimized derailleurs:

  • SRAM Force D1 and D2 eTap AXS Rear Derailleur short cage (33T max)
  • SRAM Red D1 eTap AXS Rear Derailleur short cage (33T max)
  • SRAM Force D1 and D2 eTap AXS XPLR Rear Derailleur
  • SRAM Red D1 eTap AXS XPLR Rear Derailleur

Pending further testing, this cage does not fit Apex AXS, Rival AXS, or Red E1 XPLR rear derailleurs.

The cage includes 12T aluminum pulleys on stainless bearings. You can add most aftermarket 16T pulleys for lower chain friction.

Installation requires a chainring nut tool or dedicated 4-tooth AXS cage removal tool; and 2.5mm hex wrench. Other brands' OSPW cage installation videos can walk you through the process. If you'd like Cycles Chinook to install the derailleur cage for you, just ship us your rear derailleur when you place your order. We can usually send them back out the same business day.
