Mechanical necessities such as the carbon cage, ceramic disk bearings and anodised aluminum artistically merge with proprietary electronic advances to deliver a small shifting miracle.
Using 128-bit encryption, eTap shift signals are transmitted and received according to SRAM's proprietary wireless protocol known as AIREA. Each time an eTap group is paired, a new encryption key is generated and assigned to the components in that group to ensure complete security.
Wireless shifting, battery power management and mechatronics - RED eTAP technology has one goal: to provide you with the most intuitive operation possible. SRAM designates the shifting logic behind it as eTAP. The right lever shifts into the larger gear, the left lever into the smaller gear. You can control the chainrings with both levers. Simple, smooth and intuitive.
