SRAM RED eTap AXS 1x12 Upgrade Set Road

consisting of:

• SRAM RED eTap AXS Shift-Brake-Control left/right
• SRAM RED eTap AXS rear derailleur 12-speed
• SRAM charger

The SRAM RED eTap AXS™ is much more than an evolution. It is a 12-speed revolution. The developers of SRAM created a groupset that is as capable as today's riders and the bikes that they choose. It offers more range, a smoother gear progression, as well as smarter shift settings —enabled by AXS™ and the simplicity of eTap® shift logic—so that you are always in the right gear. 
AXS™ (Access) allows you to easily personalize the groupset right from your phone and enable your choices while riding. The SRAM AXS™ app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.
