SRAM Red eTap HRD Group Post Mount WiFli

SRAM's wireless eTap has been completely unleashed, with many pre-packaged mini-groups that all you to move to the ease and simplicity of eTap in a single purchase. In this kit you get the Red eTap hydraulic road disc brake system for post mount style disc interfaces and the expanded range of the WiFli rear derailleur. SRAM developed their low power and secure wireless connection via AIREA™ network for fast and clean installation.

With the Red eTap HRD Group Post Mount WiFli, you will get left and right Red eTap Shifter/Brake levers with the hydraulic brake set-up, including front and rear pre-bled post mount style calipers. The hydraulic system is pretty straightforward to bleed and service, though most users will opt for a top-level shop mechanic to shorten hydraulic housing. Along with the levers and calipers SRAM supplies two of their well engineered and lightweight 160mm Centerline two-piece six-bolt disc rotors and mounting bolts.

eTap is powered with coin cell batteries in the shifters, as well as compact rechargeable batteries on the front and rear derailleurs. The included Red eTap front derailleur is the braze-on type and delivers the best SRAM front shifting experience to date. The Red eTap WiFli rear derailleur is compatible with cassettes featuring 32T large cogs, so you get Exact Actuation shifting with great overall range and precision responses no matter what the combination. This mini-group does not include a cassette, but Red eTap WiFli is designed to work with SRAM PowerGlide and PowerdomeX cassettes.

Of course you will need to charge the FD and RD batteries, and the eTap Battery Charger and Power Cord are in the box, as well as the set-up USB Stick and QuickStart Guide. If you are looking to upgrade your Red 22 drivetrain to eTap for use with post mount hydraulic disc brakes, this packaged set-up will deliver impeccable wireless electronic shifting and hydraulic disc brake to your cross, gravel or road bike.
