SRAM’s own wireless technology provides a secure connection & the removable battery has a 1000km range. So, if you forget to top up your battery & it runs low miles from home, simply swap it over with the front derailleur's battery to get back on the road with a full cassette range. It also benefits from the same quality construction of the mechanical SRAM Red version, featuring ceramic pulley bearings, a carbon cage, & an anodised alloy body. Technologies: AIREA™
- Utilizing 128-bit encryption, e Tap shift signals are transmitted & received in accordance with SRAM’s proprietary wireless protocol known as AIREA. Each time an e Tap groupset is paired, a new encryption code is generated & assigned to the components in this group to ensure complete shifting security. e TAP
- All of the underlying tech in the SRAM RED e Tap groupset such as wireless shifting, advanced battery power management & mechatronics technologies are all meant to serve one ultimate purpose, to facilitate the most intuitive & consistent shifting available. This shift logic is called e Tap. Right lever makes it harder, left lever makes it easier, both levers shift the front derailleur. Simple, unmistakable, & intuitive. Exact Actuation: When SRAM launched their road technology from scratch they reapplied their MTB proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/stabilise the uneasy act of balancing rear derailleur hanger design, tight cog spacing & exact cable tension. The result: the easiest index shifting system to set up & it stays that way.
