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.
When we launched our road technology from scratch we reapplied our MTB proven SRAM 1:1 actuation ratio (shifter cable travel : derailleur movement) for 10 speed rear shifting. EA 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.
With a front derailleur cage that rotates to maintain a consistent angular relationship with the chain, Yaw technology eliminates the need for shifter trim. As a result, shifts feel more direct and precise, delivering an unmatched performance advantage in front shifting.
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.
The Road kit includes:
- Front and rear derailleurs (with batteries)
- Left and right shift/brake levers
- eTap Battery Charger
- Firware update dongle
