As cyclists, we design the products we want on our bikes. The Ratio 12-Speed Wide Ratchet allows you to operate an 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 Eagle™ cassettes
- M2.5 screw for shifter ratchet replacement
- Ratio chainstay sticker
To fit this ratchet you will need SRAM 11-speed shifters from the Red™, Force™, Rival™, Apex™ or S Series™ groups.

NOTE: On some older shifters, the reach adjuster will not spin freely when it bottoms out. Stop turning the reach adjuster screw as soon as you encounter resistance.
