Cable Fin B

SRAM X Actuation* cable fin, adjusted for SRAM AXS/XPLR* sprocket spacing.

Use Ratio Cable Fin B to convert a SRAM 1x-specific derailleur to SRAM AXS/XPLR* spacing with SRAM X Actuation* shifters. This cable fin uses a variation of SRAM X Actuation* cable pull to allow you to use an Eagle-spaced 12 speed shifter (SRAM MTB, SRAM Apex 12 speed) with a SRAM AXS* or XPLR* cassette, which uses a different variation of 12 speed sprocket spacing.

If you need to convert your SRAM 1x-specific derailleur to SRAM Exact Actuation*, in order to use 10 or 11 speed road shifters, check out Cable Fin A.


SKU: 0080 Category:

The fin is not compatible with derailleurs where the original fin is fitted with a rivet. This includes SRAM Eagle* SX* and NX* derailleurs.

Included you will find:

  1. Ratio Cable Fin B
  2. Spare circlip
  3. Ratio chainstay sticker
