What’s it for?
Upgrade your SRAM 1×11 drivetrain to wide-range, mechanical 1×12 using SRAM Eagle components. The rear exit version of the kit allows you to fit an Eagle derailleur to frames where it wouldn’t otherwise be possible – for more information, check the “Forward vs. Rear Exit” section of this guide.
What’s in the kit?
The 1×12 Wide Rear Exit kit includes a 1×12 Wide ratchet for Eagle 12 speed indexing, a cable fin to convert Eagle or Apex XPLR derailleurs to SRAM Exact Actuation* (allowing them to work with SRAM road shifters) and a Rear Exit cable stop to change the cable routing on your Eagle* derailleur. There’s also a plug to keep dirt out of the original cable port.

Green – Recommended
Amber – We’ve tested some of these and, for derailleurs in particular, some options will be an issue. These issues are related to jockey wheel clearance and total derailleur range of movement.
Red – Not recommended
