Bringing together two separate, highly innovative technologies into one comprehensive and cohesive component option for the forward thinking rider, the SRAM Red eTap HRD Post Mount Wireless Groupset assures you of seamless wireless shifting as well as modulated braking force, giving you the ultimate equipment to build out your modern road racing machine.

SRAM Red eTap HRD Post Mount Wireless Groupset

The biggest innovation in shifting technology since the invention of the derailleur, SRAM's wireless Red eTap system is universally lauded as the high tide for componentry in the digital world. Not satisfied to rest on their laurels in the SRAM Red eTap HRD Post Mount Wireless Groupset, they go further, melding their impressive wireless shifting with the unparalleled accuracy of the brand's HRD hydraulic road disc brakes, giving you the same metered performance when stopping as well as cranking up the tempo.

Equipping you with the all important redesigned levers that integrate two seperate technologies in order to assure you of the best possible riding experience, this system assures you of the cleanest and most measured possible shifting experience. The levers allowing a simple click to select your gearing with minimal effort, you can be assured of an instant and responsive drivetrain. Compatible with 11-speed cassettes, this precise and honed approach to gearing allows you to leave wiring behind, reducing weight on your ride and improving your experience by bike.

Shipped including a front and rear derailleur, both equipped with a battery, you can be sure that movements across your cassette and chainset will be milimeter accurate at each and every juncture. Strong, smooth, and silkily transferring between your gears, you will need little confirmation that this is the world's leading shift technology.

The greatest innovation in this groupset relevant to the hydraulic disc brke calipers, SRAM have re-engineered their HRD model to offer greater clearances, as much as 0.4mm, you can be sure that disc rub is eliminated, giving you only the benefits of disc braking without any of the downsides. A modulated braking experience offering a powerful stopping force for most any rider, this integrated system delivers a better performance than previous models, stopping you faster while giving you the confidence to lean into that corner at greater speed.
