This ratchet allows you to upgrade your 11 speed mechanical SRAM shifters to 12 speed. You can pair your upgraded shifters with a SRAM Exact Actuation™ derailleur and a cassette with Eagle™ sprocket spacing. This is the neatest solution on the market to gaining all the performance advantages of a wide-range 1×12 drivetrain on a gravel, road or touring bike without the expense of electronic shifting.
This product ONLY contains the ratchet. If you require a cable fin too then please see our upgrade kits, 1×12 Upgrade Kit – Forward Cable Exit and 1×12 Upgrade Kit – Rear Cable Exit. For more information on kit compatibility, check our compatibility guide.
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.
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.
