What’s it for?

Upgrade your SRAM 1×11 drivetrain to wide-range, mechanical 1×12 using SRAM Eagle components. The Forward Exit version of the kit leaves the Eagle derailleur cable routing unchanged, but isn’t compatible with all frame designs. For more information, check the Forward vs. Rear Exit section of this guide.

What’s in the kit?

The 1×12 Wide Forward Exit kit includes a 1×12 Wide ratchet for Eagle 12 speed indexing, a cable fin to convert Eagle derailleurs to SRAM Exact Actuation (allowing them to work with SRAM road shifters) and a cable adjuster that slots into the derailleur’s 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
