SRAM RED eTap AXS HRD D1 HRD Kit 1x12-speed black

The new SRAM RED eTap AXS is much more than an evolution. It's a revolution. SRAM created a groupset that's as capable as today's riders and the bikes that they choose. It offers more range, a smoother gear progression, and the simplicity of eTap shift logic—so that you're always in the right gear. AXS allows you to easily personalize the groupset right from your phone and enable your choices while riding. Orbit technology offers next-level chain management for all the places a drop bar bike can go.

AXS
AXS is SRAM's new electronic integration platform that combines electronic bicycle components and software. The SRAM AXS app allows riders to view battery status, change component behavior, adjust controls, receive maintenance reminders and firmware updates.

X-Range
Racing bikes are faster and more powerful than ever before and riders keep showing what bikes with racing handlebars are capable of. X-Range offers a wider range of gear ratios, as well as an even more pleasant and usable gear gradation... and also has smart, programmable shift settings thanks to AXS.

Orbit
Orbit technology is an innovative new form of rear derailleur motion control. It uses silicone fluid as part of an elegant and ultra-light damping system. Compared to a conventional friction clutch system, Orbit technology produces no additional resistance to the rear derailleur spring during slow or light movement. This means easier shifting and rear wheel removal. During the ride, the fluid damper holds the chain back in a refined and elegant way. With maximum reliability and chain tension, for 2-fold and 1-fold systems.
