cable fin B
What’s it for?
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.

cable fin compatibility:
- SRAM Eagle derailleurs from the GX*, X01* and XX1* groups
- SRAM Apex Eagle
- SRAM 1×11 derailleurs (only if the existing cable fin is held on with a circlip)
- SRAM Eagle derailleurs from the NX* and SX* groups (the cable fin on these derailleurs is not replaceable)
