When SRAM, a leading brand in the cycling industry, introduced the ETAP (Electronic Tap) groupset, it sent shockwaves throughout the cycling community. The notion of wireless shifting was revolutionary, and many were left wondering – is SRAM ETAP wireless? In this article, we’ll delve into the world of wireless shifting, exploring the technology behind SRAM ETAP, its benefits, and what makes it a game-changer for cyclists.
The Dawn of Wireless Shifting
Traditional mechanical shifting systems have been the norm in the cycling industry for decades. While they’ve served riders well, they have their limitations. The introduction of electronic shifting systems, like Shimano’s Di2 and Campagnolo’s EPS, marked a significant shift towards innovation. However, these systems still relied on cables and wires to connect the components.
SRAM took a bold step forward by introducing a wireless shifting system that eliminated the need for cables and wires altogether. The ETAP groupset uses a proprietary wireless protocol to communicate between the shifters, derailleurs, and batteries. This revolutionary design allows for a cleaner, more streamlined setup that reduces weight, improves aerodynamics, and increases overall reliability.
How SRAM ETAP Wireless Shifting Works
So, how does this wireless magic work? The SRAM ETAP system consists of three primary components:
- Shifters: The shifters are equipped with a wireless transmitter that sends signals to the derailleurs.
- Derailleurs: The derailleurs contain wireless receivers that communicate with the shifters and execute the shifting commands.
- Batteries: The batteries power the system, providing the necessary energy for the wireless communication to take place.
When a rider initiates a shift, the shifter sends a signal to the derailleur, which then adjusts the gear accordingly. The batteries, located in the derailleurs and shifters, provide the power necessary to facilitate this wireless communication.
SRAM’s Wireless Protocol: Airtag
SRAM developed a proprietary wireless protocol called Airtag, which ensures reliable, interference-free communication between the components. Airtag uses a combination of algorithms and frequency hopping to minimize the risk of interference from external sources, such as other wireless devices or radio signals.
Airtag’s advanced protocol also enables features like:
- Signal Strength Indicators: The shifters display a signal strength indicator, providing riders with real-time feedback on the connection between the components.
- Automatic Component Pairing: The system automatically pairs the shifters and derailleurs, eliminating the need for manual configuration.
Benefits of SRAM ETAP Wireless Shifting
So, what makes SRAM ETAP wireless shifting so appealing? Here are some of the key benefits:
Improved Aerodynamics
The absence of cables and wires results in a cleaner, more streamlined setup that reduces air resistance. This can lead to improved aerodynamics, particularly for timeTrial and triathlon riders.

So, to answer the question – is SRAM ETAP wireless? The answer is a resounding yes, and it’s an innovation that’s here to stay.
What is SRAM ETAP and how does it work?
SRAM ETAP (Electronic Tap) is a wireless shifting system designed for road bikes. It eliminates the need for traditional mechanical shifting systems, replacing them with a wireless connection between the shifters and the derailleurs. This system utilizes AIREA, a proprietary wireless protocol, to transmit shift commands from the shifter to the derailleur, allowing for precise and reliable gear changes.
The ETAP system consists of three main components: the shifters, the derailleurs, and the battery pack. The shifters transmit shift commands to the derailleurs wirelessly, which then execute the desired gear change. The battery pack powers the system, providing up to 600 hours of ride time on a single charge. This innovative design allows for a cleaner, more streamlined appearance, while also reducing maintenance and improving overall performance.
Is SRAM ETAP compatible with all types of road bikes?
SRAM ETAP is designed to be compatible with a wide range of road bikes, from entry-level to high-end models. However, it’s essential to ensure that your bike’s frame and components are compatible with the ETAP system. SRAM offers a compatibility checker tool on their website to help riders determine if their bike is compatible.
Additionally, SRAM ETAP is available in various versions, including the ETAP, ETAP AXS, and RED ETAP, each designed for specific types of road bikes and riding styles.
