油壓剎車變速桿 - Sram Red eTap HRD Shift-Brake Control

Without wires or cables, we were able to design a simpler way to shift, and the intuitive simplicity of SRAM RED® eTap® is available with the added performance of hydraulic road disc brakes (HRD). The SRAM RED® eTap® HRD shift-brake control offers the world's first wireless drivetrain with our most advanced HRD platform yet, HydroHC™. Simpler shifting, better braking-all in the name of true advancement.

• New HydroHC™ brake platform offers more control than any other road brake on the market
• Small diameter hood for more finger wrap
• Contact Point Adjustment™ lets you custom tune when your brakes engage
• An independent Reach Adjust makes it easy to adjust your brake lever position for maximum one-finger control
• Bleeding Edge™ technology for quick, hassle-free bleeds
• Class-leading heat management technologies-heat shield, insulated aluminum pistons, and a wider pad pocket-help HydroHC™ improve on HydroR™'s already impressive heat management capabilities.
• 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 installation

LEEDING EDGE
With this new caliper fluid circuitry, the bleed port has been moved to the bottom of the caliper, and all four-piston bores can communicate. This way, during bleeding fluid naturally fills the caliper, resulting in an easier, more consistent bleed.

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 Adjust, you can pick the position you want your fingers to be in when your brakes are engaged. Il's a quick and easy way to customize the feel of your brakes without having to move the pads. It's also a way to balance nee both brake levers to feel exactly the same.

Reach Adjust 握距調整功能
煞車把手貼合度與主觀意識有強烈的關係。握距調整功能，可針對多種手掌尺寸個人化設計。Reach Adjust 可輕鬆調整你的手桿，為每個人提供最大的單指控制。

eTAP 無線變速
包含我們的新款 SRAM RED® eTap 套件背後的所有科技，如無線變速、先進電池電力管理及機電一體技術，全都是為了一個終極目標，達成最為直覺且連貫的變速操作。此種變速邏輯稱為 eTap。右變把負責切換至重檔，左變把負責切換至輕檔，同時按壓則可切換前變速器。簡單、零失誤並合乎直覺。

AIREA
Utilizing 128-bit encryption, eTap shift signals are transmitted and received in accordance with SRAM's proprietary wireless protocol known as AIREA. Each time and eTap groupset is paired, a new encryption code is generated and assigned to the components in this group to ensure complete shifting security.

STEALTH-A-MAJIG
Stealth-a-majig is the coupling that makes the initial setup of hydraulic systems fast and convenient. Its smaller size allows for easier internal cable routing, giving bikes a clean look.
