As cyclists, we design the products we want on our bikes. The Ratio 1×12 Wide Ratchet allows you to run a SRAM Exact Actuation* derailleur 12 speed with your existing SRAM 11 speed road 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* cassettes
- 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.
