SRAM GX Eagle AXS Upgrade Kit 

GX Eagle AXS 12 speed Rear Derailleur Riders want a derailleur that shifts on command, whether under climbing load or sprinting to the stage finish. The GX Eagle AXS derailleur gets it done with everything you have come to expect from SRAM AXS connect components. The GX Eagle AXS derailleur is smart enough to protect itself thanks to its incredibly resilient Overload Clutch. It is engineered with a variety of rider preferences in mind, it is compatible with SRAM’s new expanded range 10-52t cassette as well as their 10-50t cassette. Showcasing its lineage from the proven GX Eagle mechanical line, the GX Eagle AXS derailleur is there for one thing – to do the job.

GX Eagle AXS 12-Speed Wireless Controller The pure shifting performance of Eagle AXS™ is now available with GX. Shift under load, over the roughest terrain, uphill, without changing your grip on the bar. GX Eagle AXS™ changes your level of control on the bike when you’re under pressure and pushing hard. More than that, it changes your relationship with the bike. No cable, housing or wires to manage opened up design and engineering possibilities with the GX Eagle AXS™ controller. Featuring the proven ergonomic touchpoints that make shifting effortless, they are customizable to your preferences, allowing you to choose which button does what through the AXS™ App.

SRAM Battery Charger SRAM batteries are literally a snap to remove and charge. Just flip the tool-free battery latch up and slide the battery up and out of the derailleur. Then snap the battery into the USB powered charger and connect the charger to any USB power source or A/C USB adaptor. A full charge takes up to 60 minutes to complete.

SRAM Chain B-Gap Tool The new B-gap adjustment tool is simple and easy to use, allowing for a quick set up experience. Small enough to be able to pack in your ride bag or stash in your toolbox for repeated use, it is also industrially recyclable if you find you no longer have use for it. This is the most precise tool for setting up and adjusting your drivetrain.
