. The SRAM Red® ETAP® HRD Shift-Brake Control levers use SRAM’s Airea™ wireless communication protocol for a secure and interference free connection with the derailleurs. Its advanced shift logic is inspired by motorsport and introduces a new way to shift that will virtually eliminate mistaking upshifts and downshifts with the added performance of hydraulic road disc brakes (HRD) Customisable Brake Feel. The HydroHC™ hydraulic disc brake platform features top-of-the-range heat management technologies such as a heat shield, insulated aluminium pistons and a wider pad pocket. All of this helps to improve upon the already impressive heat dissipating properties of the HydroR™ platform. The feel of the SRAM Red ETAP HRD Shift-Brake Control can be customised using the Contact Point Adjustment™ and Reach Adjust technologies Ergonomically Shaped. The shifters are powered by two CR2032 watch batteries, which are good for 2 years of use. Ergonomically shaped hoods sit comfortably in the hand and the levers are reach-adjustable to suit all hand sizes Features: Lever Material: Carbon Compatibility: SRAM Red® ETAP® derailleurs, SRAM 11-Speed road crankset, chain, and cassette compatible HydroHC™ brake platform offers more control than any other road brake on the market Improved ergonomics including a smaller diameter hood for more finger wrap Contact Point Adjustment™ lets you custom tune when your brakes engage Independent Reach Adjust makes it easy to adjust your brake lever position for maximum one-finger control Bleeding Edge™ technology for quick, hassle-free maintenance Responsive lever feel for better control, featuring a light lever stroke with distinct contact point and snappy return SRAM ETAP® shift logic for intuitive and reliable shifting Wireless connection via Airea™ network for fast and clean installationTechnologies: Airea™: Utilising 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. ETAP®: All of the underlying technologies in the 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®. The right lever makes it harder, the left lever makes it easier, press both levers to shift the front derailleur. Simple, unmistakable, and intuitive. Bleeding Edge™: Bleeding Edge™ technology makes bleeding brakes quick and simple. An updated fluid path and bleed porting make it easier to push fluid through the caliper. A dedicated bleed adapter plugs into the bleed port and seals the system to minimise air contamination and fluid loss. Contact Point Adjustment™: Some people like the instantaneous power of a short lever throw. Others prefer the feel of a longer throw. With Contact Point Adjustment™, you can pick the position you want your fingers to be in when your brakes are engaged. It’s a quick and easy way to customise the feel of your brakes without having to move the pads. It’s also a way to balance both brake levers to feel exactly the same. Reach Adjust: Brake lever fit and feel is a personal thing. Riders have individual positioning preferences, as well as unique hand sizes and finger lengths. Reach Adjust makes it easy to adjust your lever for maximum one-finger control for everyone. Stealth-a-majig™: Stealth-a-majig™ is the coupling that makes initial setup of hydraulic systems fast and convenient. Its smaller size allows for easier internal cable routing, giving bikes a clean look Buy SRAM Components from Chain Reaction Cycles, the World’s Largest Online Bike Store.
