NX Eagle 12-Speed Rear Derailleur
The NX Eagle 12-Speed Rear Derailleur provides the same precise, reliable performance you expect from Eagle, with the lowest barrier to entry we've seen yet. It shares the same technology as its pricier GX, XO1, and XX1 counterparts, but uses more budget-friendly materials for its construction. The best part is that it's compatible with all levels of Eagle drivetrain, giving you an affordable replacement option if you manage to bust your derailleur on a rock or break it during a crash.
Instead of the carbon or aluminum cages found on the higher-end Eagle derailleurs, NX uses a steel cage to keep the cost down without sacrificing durability, though this does come with a minor weight penalty. It has the same X-Horizon design that eliminates ghost shifting and reduces shift force, as well as the 14t X-Sync lower pulley that facilitates the 10 - 50t or 11 - 50t cassette capacity. Continuing with SRAM's signature technologies, X-Actuation and the Type-3 Roller Bearing Clutch work together to provide quick, seamless shifting with quiet operation and no chain slap. It even has the Cage Lock button that lets you lock the derailleur in place to slacken the chain, simplifying wheel removal and installation.

I run this derailleur on a road bike with a Campy Chorus 12 speed drop bar right shifter , 1x12 with a 10-50 12s Chinese cassette and it shifts just about perfectly. Dude at the LBS suggested the build and I did not believe it until I did it . No ghost shifts, no drops, no jumps, no problem, it plunks hard down on the 10 tooth cog but it works. Picks up, goes down just like normal Campy . I would buy a GX level but its pricey. Campy 12s chorus really sucks compared to 11s Chorus, which was the best chorus ever. Now I am converting my several chorus 12 bikes to this build. It has a wider range than the 2x build I was using before. If they tell you there is no 12s drop bar mullet for eagle, they just do not know , because this works perfectly.
