SRAM eTap AXS™ - just keep going

An even more capable groupset for today's generation of riders

As drivers, we are doing more today than ever before. We drive further and we drive faster. And when the road ends, we just keep going. But one thing hasn't changed: We want to keep pushing the boundaries of what's possible and don't let anything distract us. It has never been so easy to explore new things. SRAM eTap AXS™- Just keep going.

Modern shift stages

Always in the right gear

X-Range™ offers a wider range of gear ratios and closer spacing, so you're always in the right gear.

Quiet, safe and pleasant

The Orbit™ chain management and the Flattop™ chain ensure an exceptionally quiet, safe and pleasant driving experience.

Simply customized

AXS™ offers unprecedented shifting performance, completely new customization options and insights into your bike's performance.

Road bikes are faster and more capable than ever before, and riders continue to show what road handlebar bikes are capable of. X-Range™ offers a larger gear range, as well as an even more pleasant and usable gear stepping... and thanks to AXS it also has smart, programmable shift settings.

Pleasant gear jumps

Whether on asphalt or the gravel track, 1x or 2x - eTap AXS guarantees a quiet, safe and pleasant ride. Thanks to the Orbit liquid damper and SRAM's unique Flattop chain, you'll ride more confidently and efficiently than ever before - no matter what the terrain.

AXS™ possibilities

control and customization. AXS™ is SRAM's newest system for integrating bicycle components and takes eTap® wireless shifting to a new level. The SRAM AXS™ app not only allows the driver to call up the battery level and change the shifting behavior. You can also use it to customize the controllers, get maintenance reminders, and get firmware updates.

eTap Gravel

If you can't get enough of the crunching of the gravel under your tires, then SRAM has exactly what you need with the AXS.

Driven by professionals

Today's pro racers are going faster than ever before. It's about time there was a drive group that met their needs.

Even more aerodynamic

The smaller eTap BlipBox can be easily integrated into aero frames or the new Zipp Vuka Aero Bar. It not only ensures a tidy look, but also improved aerodynamics.

The new paradigm in performance measurement

By integrating the Quarq DZero Power Meter into SRAM's chainrings, they've made power measurement cheaper and more accessible - and lighter too.

Even off the road

With the AXS™, racing bike and MTB components can be freely combined with each other. How about a road bike groupset and a dropper post on a gravel bike, for example?

Technologies used

In this chapter we explain the technologies that the manufacturer uses in this product.

AXS™
AXS™ is SRAM's new integrated platform for connecting electronic bicycle components with software. The SRAM AXS™ app not only allows the rider to check the battery level, influence shifting behavior and configure the controls according to personal preferences, but also to create maintenance plans and update the firmware.

Carbon Tuned™
Strength and stiffness where you need it, light weight where you want it. The SRAM design with the exclusive carbon coating increases the thickness and rigidity in areas with particularly high loads. The tapered, stepped carbon architecture ensures maximum weight savings without sacrificing strength.

DUB™
The ratio of how the crankshaft and the bearings are dimensioned here is the core of the DUB™ technology. This is where rigidity and durability meet and complement each other. SRAM has simply thought a little further and made everything even easier - by better integrating all components such as the chainring, crank, crankshaft and bottom bracket. Only this approach, to see the drive as an overall system, enables better drive performance.

DZero™
Quarq's Dzero power meter platform is named after the "D0 Experiment" - one of the most accurate and innovative science projects to detect subatomic particles moving at the speed of light. With a new measurement circuit, a revised strain gauge (SG) design, improved accuracy throughout the crank revolution and the most advanced software, DZero represents the state of the art in power measurement technology.

Flattop™
SRAM has developed a narrower chain specifically for the X-Range™. The unique shape of the chain links in Flattop technology not only enables a larger gear range, it also ensures quieter chain operation, greater stability and improved durability.

Flow Link™
The chain's ultra-smooth inner plates are completely free of edges. This reduces the friction on the cassette and chainring. The result: low-noise performance and a longer service life for the components. Chain design allows for a slimmer profile. The chain is more torsion-resistant. Thanks to their smooth outer plates, the riveting is more even and the tensile strength is higher.

Orbit™
Orbit™ technology is an innovative and new way to control derailleur movement. It uses silicone fluid as part of a sleek and ultra-lightweight damping system. Compared to a traditional friction clutch system, Orbit Technology puts no additional drag on the derailleur spring during slow or light movements. This means easier shifting and simplified wheel removal. And while riding, the fluid damper reduces chain slap. That means bombproof reliability for 1x and 2x drives.

PowerLock
SRAM's chain engineers developed PowerLock as a tool-free, secure and consistent way to connect their chains. Although the PowerLock does not require any special tools for assembly, given the narrow tolerance range of a 10, 11 and 12-speed drivetrain, each PowerLock can only be used once.

XDR™
The XDR™ driver is a universal interface for cassettes with single sprockets under 11 teeth. This allows lighter and more versatile drives to be implemented without the need for a new rear hub standard, a change in the hub body or the cassette tool. The XDR™ interface is 1.85mm wider than XD™ and was developed for racing use. The XDR drivers are compatible with all XD cassettes as long as you install the cassette with a 1.85mm wide spacer.

X Range™
Road bikes are faster and more capable than ever before, and riders continue to show what road handlebar bikes are capable of. X-Range™ is the translation for the modern way of riding road bikes. SRAM has completely redesigned the road bike transmission, for more range of transmission, a more pleasant and better usable gear stepping and, thanks to AXS™, also smarter shift settings. With X-Range™ you are always in the right gear.

X Sync™
X-Sync™ 1x chainrings from SRAM ensure maximum performance and durability. Long SRAM X-Sync™ tooth edges engage the chain earlier than traditional triangular teeth. The sharp and narrow tooth profile as well as the rounded sloping edges support the chain guidance. In order to offer the best possible performance even in muddy terrain, the X-Sync™ chainrings have recesses for the inner chain links and rollers to evacuate dirt and debris. Made in Germany, X-Sync™ chainrings are an important part of SRAM's 1x™ drivetrain.
