SRAM GX Eagle 12 Speed Rear Derailleur



Perfect for cross country (XC) and enduro, the SRAM GX Eagle 12 Speed Rear Derailleur offers powerful shifting operation and control, whether you're climbing or descending. It's ready for 10-52 tooth cassettes and has excellent chain retention.


Designed for versatility, the SRAM GX Eagle rear derailleur features a robust aluminium inner and outer cage construction, which makes it more than ready to tackle whatever the off-road has to offer. SRAM has also equipped this tough mountain bike (MTB) rear mechanism with steel pulley bearings for additional durability on every ride.

Developed around a backwards-compatible profile, this model works with both 10-50T and 10-52T cassettes for greater flexibility. Another benefit is its updated cage design that delivers greater chain retention than before and even more precise shifts, as you weave between the trails. The SRAM GX Eagle rear derailleur - 12 speed looks as amazing as it performs.

- Backwards compatible, works with both 10-50T and 10-52T cassettes
- Updated cage architecture provides better chain retention and precise shifts
- Comes in GX Eagle™ master colourway as part of Eagle™ Colour system and goes with all colours of Eagle cassettes and chains

Riders want the derailleur to do its job shifting on command, whether under climbing load or the stage finish. The GX Eagle™ derailleur gets it done with an updated cage architecture that improves chain management. Refined to work with the 10-52T cassettes, it’s also backwards compatible with the 10-50T versions. Giving riders choice, because that’s how it should be. Finished with the updated GX Eagle™ master colourway – to complement any cassette and chain colourway a rider wants from the Eagle™ Colour system. Further proof that the GX Eagle™ derailleur is there for one thing - to do the job.
