Ratio Technology Cable Fin


Use the Ratio Cable Fin to match an X-Actuation™ 1x SRAM derailleur to Exact Actuation™ SRAM shifters. A barrel adjuster provides on-the-fly indexing ability for mountain bike derailleurs.

For more information on compatibility, check our guide.

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

Use a Ratio Cable Fin to convert a SRAM X-Actuation™ 1x mountain bike derailleur to Exact Actuation™. This allows you to pair the derailleur with your SRAM road shifters.

This is ideal if you’re building a wide-range one by 10 or 11 speed drivetrain and you need the sprocket size capacity of a mountain bike derailleur with road shifters.

Included you will find:

  1. Ratio Cable Fin
  2. Spare Cable Fin circlip
  3. Ratio cable adjuster, providing indexing ability on a mountain bike derailleur
  4. Ratio chainstay sticker

To fit your cable fin to an Eagle™ derailleur, see the following video*:
