Looking for that next great upgrade for your bike? Look no further then the Sram GX Eagle Kit! This is by far one of the most popular upgrades these days as it has made Sram's amazing 12 speed Eagle drivetrain affordable for every biker.

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 derailleurs. 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.

SRAM 12-Speed GX Eagle Groupset with Cassette, Shifter, Derailleur and Chain.

This kit has 4 parts to make it simple to upgrade your drivetrain to the new 1x12 SRAM GX Eagle system. Whether you are dropping your front derailleur system or going from a 1x11 to 1x12, this new group will give you a 500% gear range while keeping the simplicity of the 1x system. It shifts crisp and works as good as it looks.
