Among the biggest announcements at last week’s Eurobike trade show (though not a surprising one) was SRAM’s unveiling of a disc brake version of its Red eTap drivetrain. The electronic and wireless HRD takes SRAM’s road hydraulic braking platform and melds it with the burgeoning braking system. It was one of 12 Eurobike Gold Award winners.

Utilizing SRAM’s new HydroHC brake platform, SRAM Red eTap HRD combines the performance and control of hydraulic disc brakes with the adjustability of conventional rim brakes. With both contact point adjustment and independent reach adjust, regardless of hand size or brake feel preference, riders can achieve their preferred brake setup.

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 customize 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. Riders also 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.

This adjustability is matched with SRAM’s well regarded brake modulation control and heat-management technology, making the most harrowing descents far less harrowing.

Improved ergonomics, include a smaller diameter hood for more finger wrap.

SRAM also simplified brake setup and maintenance with its new Stealth-a-Majig brake hose fitting that’s paired with a revised hose barb and new threaded olive to make initial setup fast and easy. Likewise brake fluid-management technology enables quick and consistent brake bleeds. This is all combined with the intuitive shifting of SRAM Red eTap.

See how easy it is to install a SRAM Red eTap drivetrain.

Other highlights include improved ergonomics, including a smaller diameter hood for more finger wrap and heat-management technologies in the form of heat shield, insulated aluminum pistons, and a wider pad pocket to improve cooling.

A complete kit includes shift-brake controls and calipers, front derailleur with battery, rear derailleur with battery, battery charger, cord, adapters for US/EU/GB/AUS, USB firmware update dongle, and  CenterLine XTM Rotors 160mm with Ti hardware.

Wireless connection is achieved via SRAM’s Airea network for fast and clean installation and use. Utilizing 128-bit encryption, eTap shift signals are transmitted and received in accordance with SRAM’s proprietary wireless. 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.
