SRAM Eagle just got a little better now with extended range! If Eagle just isn't enough for you they've now added 2 teeth to the cassette! If you need a little extra help on the climbs but don't want to sacrifice your top speed by dropping the front ring this is just what you need! Upgrading or setting up a 10-52 Eagle drivetrain? You will need a new derailleur since the added range is just a little too much for the 10-52 derailluers. That means if you are getting the new cassette you will want one of these. If you've still got some life left in your drivetrain, don't worry, that Eagle shifter and chain you have is still good to use for the extended range!
The GX Eagle Rear Derailleur gets the job done with a thoughtfully designed cage architecture that improves chain management.

  • Will not work with front derailleur drive trains
  • Mounting system and re-positioned Cage Lock offer greater durability
  • Sealed cartridge pulley bearings
