Ratio - 1x12 Wide Upgrade Kit - Rear Exit
This upgrade kit allows you to pair 11 speed mechanical SRAM shifters with a 12 speed SRAM Eagle* derailleur and cassette. This is the neatest solution on the market, giving you all the performance advantages of a wide-range 1×12 drivetrain on a gravel, road or touring bike without the expense of electronic shifting.
Thanks to the rear-exit cable stop, this kit is compatible with all frame cable routing variations.
For more information on compatibility, check our guide.
COMPATIBLE: SRAM Eagle* derailleurs from the X01* or XX1* groups.
NOT COMPATIBLE: SRAM Eagle* derailleurs from the SX*, NX* and GX* (the cable pulley is riveted in place).

As cyclists, we design the products we want on our bikes. The Ratio 12-Speed Upgrade Kit allows you to operate a SRAM Eagle* derailleur with your existing SRAM 11-speed shifters, gaining an unbeatable 500% or 520% range and 12 evenly spaced gears on your gravel, road or touring bike. For reference, a traditional 50/34 compact chainset with 11-28 cassette provides only 374% range.
In your kit you will find:
- Ratio 12-speed ratchet, with shift spacing specially designed for SRAM Eagle* derailleurs
- Ratio cable fin, replacing the existing cable fin on a SRAM Eagle* derailleur
- Ratio rear-facing cable stop with adjuster, routing the cable out of the back of the derailleur for compatibility with all frame designs
- Cable Stop fitting screw
- Spare cable fin circlip
- M2.5 screw for shifter ratchet replacement
- Ratio chainstay sticker
To use this kit you will need:
- SRAM 11-speed shifters from the Red*, Force*, Rival* or Apex* groups or the 10-speed S-700* shifters.
- A SRAM Eagle* derailleur from the XX1* or X01* groups. GX* derailleurs are NOT COMPATIBLE with the cable stop as the cable pulley is riveted in place – you can find a pre-fitted SRAM GX* derailleur in our 1×12 Wide Upgrade Kit + Rear Exit SRAM GX* Derailleur. The kit is NOT COMPATIBLE with SX* and NX* derailleurs as the cable fins on these derailleurs are riveted in place.
- A SRAM Eagle* 12 speed cassette. We can’t confirm that aftermarket cassettes will perform properly with your drivetrain.
- A 12 speed chain for SRAM Eagle* drivetrains.
- A 1×12 speed compatible chainring.
