The SRAM NX Eagle rear derailleur makes 12-speed 1x MTB gearing accessible at the entry level — the full 10-52T Eagle range in a derailleur compatible with standard HG freehubs via the PG-1210 cassette, removing the XD driver requirement that applies to other Eagle cassette options. A practical way into Eagle gearing without wheel upgrades.

Highlights

• 12-speed Eagle rear derailleur — NX entry tier
• Compatible with PG-1210 cassette on standard HG freehubs — no XD driver needed
• 10-52T Eagle gearing range
• X-ACTUATION cable pull for consistent indexing
• Compatible with NX Eagle trigger shifters

NX and HG freehubs

NX Eagle is the one tier in the Eagle range that works with a standard HG freehub via the PG-1210 cassette — the 11T smallest cog (instead of 10T) allows the cassette to fit the existing spline interface. It's slightly heavier than XD-driver cassettes but removes a barrier for riders who don't want to swap out their rear wheel or freehub body.

Fit and compatibility

12-speed Eagle rear derailleur. Use with NX Eagle PG-1210 cassette for HG freehub compatibility, or standard XD driver Eagle cassettes. Compatible with NX Eagle trigger shifters. Confirm maximum cog capacity before ordering.
