The AXS Aero Advantage

SRAM eTap AXS™ now gives triathletes and time trialists more choices to configure their perfect drivetrain. Our X-Range™ gearing offers wider range and more useful gear progression, more shift settings and more options than ever before.

The aerodynamics and simplicity of a 1x drivetrain have now come to electronic shifting. By pairing the 330% range of a 10-33 cassette with a 48 or 50 tooth direct mount chainring, you’ll always be in the right gear on your favorite course. Five 1-tooth jumps in the sweet spot of the cassette allow you to fine tune your power output at critical moments, with more meaningful jumps available as the road goes up. A fluid damper in the rear derailleur provides lightweight chain management. And the Quarq DZero™ power meter integrated into the ring provides accurate power measurement (+ or – 1.5%) in an accessible and lightweight package.

If you like 2x drivetrains, the closer chainring combinations and 10-tooth start cassettes of X-Range gearing mean tighter jumps while still offering more range. Enhanced shift options, like fully sequential shifting, or an automatic compensating shift, can be turned on with the AXS app, your control center for tailoring your drivetrain specifically for you.

The BlipBox is smaller and can be more easily hidden in a TT/tri bike, including in the specifically designed nosecone of the new Zipp Vuka Aero handlebar. With the AXS app, Blips and Clics can be assigned the functionality that you choose. The S-900 Aero HRD hydraulic disc brake provides the ultimate in power and modulation for today’s disc-equipped superbikes.
