For SRAM, the electronic RED® eTap AXS™ shifting system is no less than a revolution. Maximum performance combined with ultimate flexibility were part of the engineers’ requirement specification. For the first time in the history of the US-American component manufacturer, a road bike shifting system has a total of 12 sprockets at the rear wheel.

The SRAM RED® eTap AXS™ Aero shift kit is an optimised version that is specifically developed for your aero bike or triathlon racer. In contrast to the standard version, the shift and brake levers of this version are replaced by Blips™ and Clics™.

Thanks to the X-Range™ technology, the RED® eTap AXS™ not only impresses with smoother shifting, but also with an improved gear ratio that helps combine small gear steps with a wide range of gears in a clever way. Yet, the proven and intuitive eTap shifting logic remained unchanged. In addition, SRAM now offers the possibility to connect the shifting system to the AXS™ app and to customize it. You can now choose for example between a sequential and a compensating shifting mode or determine the number of shifted sprockets in the Multishift mode. In addition, the electronic integration platform allows you to monitor the battery status, adjust the controllers, receive maintenance reminders and update the firmware. In short – with the RED eTap AXS™ by SRAM, ambitious cyclists will finally enter the digital age!

• Completely wireless, electronic road bike shifting system
• Optimised version specifically designed for aero and triathlon bikes
• For 1x12 speed configuration
• All electronic components in one package (read what’s in the box below)
• Part of SRAM’s AXS™ integration platform
• X-Range™ technology
• Orbit™ technology

Blips™, Clics™ and AXS™ Blipbox

It’s time to shift forward.
This special aero version of the RED® eTap AXS™ shift kit comes without the shift and brake levers that are usually fitted as standard. Instead, your control centre consists of Blips™, Clics™ and the AXS™ BlipBox. Blips™ are individually positioned on the base bar or aero bar extensions and allow for comfortable shifting in accordance with the rider’s preferences and position on the bike. Clics™ are used to fit Blips™ into the ends of the extensions. They allow you to comfortably change gears with your thumb or finger when riding in an extremely aerodynamic riding position, without having to change the position of your hands, The AXS™ BlipBox is centrally positioned on the stem/bar. It accommodates the cables and serves as an interface to the rear derailleur.

Rear derailleur

The RED® eTap AXS™ rear derailleur is an interactive masterpiece featuring a long list of top technologies for more silent and more efficient road shifting. The single rear derailleur covers all possible gear combinations (including single speed and double speed).
A particular highlight is the SRAM Orbit™ technology. A rear derailleur movement control mechanism that uses a special silicone fluid as part of the damping system. Compared to standard roller bearing clutch mechanisms, this technology creates no additional resistance at the spring of the rear derailleur. This allows for smoother and faster shifting. Besides, the fluid damper reliably maintains chain tension while riding for maximum chain control even in rough terrain.

• Material: aluminium/carbon/titanium
• Max. sprocket size: 33 teeth
• Capacity: 36 teeth
• Battery type: eTap® battery
• Weight: approx. 303 g (incl. battery)

AXS™ (pronounced “access”) is an electronic integration platform that connects electric bike components with software by SRAM.
AXS™ components communicate wirelessly using 128-bit encryption. Every time several components of a groupset are connected with each other, e.g. shifter, front derailleur and rear derailleur, a unique code is generated to eliminate the risk of interference with signals of other riders’ systems.
The SRAM AXS™ App allows you to check the status of the battery, change component behavior, customize controls, get maintenance reminders and update the firmware.
The app is available for free download in the App Store for iPhone (iOS) and in the Google Play Store for Android.
All SRAM RED® eTap 11-speed components are NOT compatible with AXS™ components and the AXS™ software!


The Orbit™ technology is a kind of rear derailleur movement control. It uses a special silicone fluid as part of an extremely lightweight damping system. Compared to standard roller bearing clutch mechanisms, this technology is speed sensitive so that slow or slight movements don’t activate the clutch mechanism. This allows for smooth shifting and easy rear wheel removal. While riding, the fluid damper reliably keeps the chain under control. With high reliability and chain tension, for double and single speed systems.


Road bikes and road cyclists are faster and more capable than ever. The X-Range™ technology offers a wider and better range of gears. Thus it provides smoother, more useful gear progression. Smart shift settings (enabled by AXS™) transfer the simplicity of singlespeed systems to double speed drivetrains. Thus, you’ll always find the right gear. Faster – more efficient – more comfortable!
