When eTap came out, it changed electronic shifting forever. However, it was only exclusive to road bikes. Now, it's available for mountain bikes with the SRAM XX1 AXS Groupset. What wasn't possible before is now here and is loaded with features like the new AXS system which gathers useful data and tells you how many shifts you have made, how frequently you use each cog, helps you make smarter choices on chainring size, and more. The simplicity and efficiency of a 1x drivetrain means you never have to worry about a front derailleur, yet you still have access to an exceptionally wide gear range.
The SRAM XX1 AXS upgrade kit includes the AXS XX1 12-speed Derailleur and AXS XX1 12-speed shifter, the two items you need to upgrade your current eagle drivetrain into an AXS drivetrain.
