At SRAM, they know that if a technological advancement clutters the experience, it shouldn't be called an advancement at all. Because it's a bicycle. It's supposed to be simple. To make something elegant to the point where it removes what's in the way... that's advancement. And that is the standard SRAM held themselves to while developing their first electronic shifting system. It's called SRAM RED eTap.
Featuring SRAM's advanced shift logic (right lever makes it harder, left lever makes it easier, both levers to change the front ring) with SRAM RED eTap you'll shift more, with less effort and spend less time doing it. Shifting has never been more intuitive or as easy as this.
And SRAM RED eTap is engineered to go the distance. It has been rigorously and successfully tested for years on the professional and WorldTour level. And now, it's ready for the rest of the world. Are you ready to shift forward?
The SRAM RED® eTap rear derailleur executes shifts the instant you demand it, with military precision. Wirelessly. It's easy to set up, clean in appearance and delightfully uncomplicated. Mechanical necessities such as a carbon pulley cage, ceramic pulley bearings, and anodized alloy artfully blend with proprietary electronic advancements to deliver a 243g (with battery) shifting wonder.
Wireless connection via AIREA network for fast and clean installation. Designed to work with SRAM PowerGlide and PowerdomeX cassettes.
They say suffering is inevitable. With SRAM WiFLi™, it doesn’t have to be. The SRAM RED® eTap® WiFLi™ rear derailleur accommodates a wider gear range - up to a 32t cassette - to help you spin up the toughest of climbs. Because the hardest way up isn’t always the fastest.
All of the underlying tech in our new SRAM RED® eTap groupset such as wireless shifting, advanced battery power management and mechatronics technologies are all meant to serve one ultimate purpose, to facilitate the most intuitive and consistent shifting available. This shift logic is called eTap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, and intuitive.
SRAM's WiFLi™ technology accommodates a wider range of gears than a standard short-cage road derailleur. Compared to a triple chainring setup, it provides faster shifts and significant weight savings.
Exact Actuation helps to simplify/stabilize the uneasy act of balancing rear derailleur hanger design, tight cog spacing and exact cable tension. The result: the easiest index shifting system to set up and it stays that way.
Utilizing 128-bit encryption, eTap shift signals are transmitted and received in accordance with SRAM's proprietary wireless protocol known as AIREA. Each time an eTap groupset is paired, a new encryption code is generated and assigned to the components in this group to ensure complete shifting security.
