Pros & Cons

  • The clutch will keep the chain on the cassette.
Read more on what our customers have to say about this product


Brand Sram
Number of gears 12-speed
Cage Length Long Cage


The Sram GX Eagle rear derailleur is provided with the same fantastic technologies as the twice as expensive XX1 Eagle derailleur. The only difference is the use of aluminium instead of carbon. With the larger 12-speed cassette the cage is also a bit longer and the lower jockey pully has 14t instead of 12. The Roller Bearing clutch is sophisticated and delivers a constant power throughout.

Amazing service, great value

Quick delivery from Netherlands to UK. It was hard to believe the price, so I was worried it would be the old model of the GX Eagle deralieur, but it was the latest model and I couldn't be happier abut the whole purchase

Cheap but rock!

This rear derailleur is the cheap solution for using 12speed, but is a good solution!

The updated SRAM GX Eagle mech

I had an early SRAM GX Eagle mech that died when the chain jumped and jammed between the cage and the jockey wheel. This replacement is the new, improved version with a ridge on the jockey wheel to prevent this happening. Best price on the internet too!

Bästa växelgruppen hittills

Har kört Shimano SLX, Sram X9 och Sram GX tidigare. GX Eagle är med god marginal den säkraste och smidigaste gruppen med marginal. Den går tyst och växlar som i smör oavsett lera eller hög belastning. Hunnit med ca 500 km i skogen med "Örnen".


  • Alla växlar man behöver på en kasett
  • Smoooth, tyst


  • Måste installeras noga, speciellt B-skruv
  • Lång cage - mindre frigång
