The SRAM RED eTap front derailleur, rear derailleur and shifters are paired together as a system so there is no interference with other nearby bikes equipped with SRAM RED eTap.
Additionally, SRAM RED eTap uses a proprietary wireless communication protocol that SRAM created called Airea. It was created and tested by computer scientists, cryptographers and even hackers to be extremely reliable and secure. It uses several layers of state-of-the-art encryption and obfuscation as well as very powerful spread-spectrum radios to eliminate the possibility of hacking the system and make interference or malicious jamming extremely difficult.
