Technological progress must prove itself in practice.
Just a bike should be easy. Elegance means renouncing everything superfluous. This is progress, and SRAM's specification for its first electronic circuit, the SRAM RED eTap.Switchgear
The SRAM RED eTap switchgear works at the push of a button - wirelessly, smoothly and precisely. Configuration is child's play. But not only its electronics are convincing: its design is straightforward and pleasantly uncomplicated. Its carbon cage, ceramic bezels and highly polished aluminium case make it a jewel of just 238g (with battery). Wireless connection through the AIREA network for quick and clean installation. Designed for SRAM PowerGlide and PowerdomeX cartridgesFront derailleur
The SRAM Yaw technology finally puts an end to the annoying trimming of the front derailleur. The SRAM RED eTAP derailleur shifts wirelessly, quickly and reliably. The eTap gear lever automatically optimises the regulation of the Yaw derailleur over the entyre gear range.Blips switch
Whether you put on a sprint at the end or climb up a pass, whether you glide with a round kick or mobilise your last reserves of power, a push of a button must always suffice to change the gear. With the eTap Blips you can switch whenever and wherever you want.BlipBox
The BipBox is the control module that turns your triathlon or time bike into a wireless bullet. Connected to the SRAM RED eTap Blip buttons, the BlipBox provides the radio connection using AIREA (the communication protocol specially developed by SRAM). Fast shifting from almost any aeroposition is possible.Charger
eTap batteries can be removed with one click. Open the shutter without tools, push the battery up and out of the rear derailleur and insert it into the USB charger. You can connect the charger to any USB-enabled power source or connect to the mains using an A/C USB adapter. The loading time is only 45 minutes.USB Stick
With the eTap USB stick, firmware updates can be transferred to the shifting group.
Wireless shifting, energy management of batteries and mechatronics - the RED eTAP technology serves one goal: to offer you 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. The chainrings you can control über both levers. Simple, smooth and intuitive.
Etap transmits the shifting signals with 128-bit encryption using SRAM's proprietary wireless protocol AIREA. If an eTap group is configured, a new encryption key is generated each time and assigned to the individual components. This ensures trouble-free shifting operations.
SRAM's WiFLi technology serves a larger transmission range than a mechanical rear derailleur with short cage. Compared to three chainrings, it ensures faster shifting and considerable weight savings.
