Lightweight AXS shift/brake system that boosts comfort and braking control

What Our Gearhead® Experts Are Saying:

“These RED levers feel incredibly natural in the hand. The hood shape is more supportive than the previous version, the braking power is easy to modulate with just a finger, and the Bonus Button integration is awesome for head-unit control. If you want the smoothest, most customizable wireless shifting experience, RED AXS is as good as it gets.”

The SRAM RED AXS HRD Shift/Brake gives our road setup a noticeable upgrade in comfort, control, and personalization. The redesigned hood shape fits a wide range of hand sizes while creating a more secure platform in both the hoods and drops, helping reduce fatigue on long training rides and steep mountain descents. The textured shift paddles offer confident feel through gloves, and the system’s ultra-light construction trims meaningful grams from the front end.

With full AXS integration, we can dial in shift behavior, button assignments, and auxiliary controls through the app, while the Bonus Button lets us operate head units or activate secondary shift points without breaking position. Hydraulic braking delivers smooth modulation and one-finger stopping power, and Reach Adjust makes it easy to fine-tune lever distance for the perfect fit. Whether we’re optimizing a race bike or refining an endurance build, the RED AXS HRD system gives us refined ergonomics and responsive performance.

Riding isn't effortless, RED is

Effortless Performance. Effortless Perfection.

You want your performance to represent 100% of what you put in, and we designed SRAM RED AXS with that goal. Every component has been refined to create an effortless ride. It’s not just the lightest electronic groupset ever; we’ve redeveloped our controls for smooth, low-effort braking and comfortable ergonomics for the widest range of hand sizes. This generation of RED also has faster and more precise front shifting, fully wireless connectivity, and expanded gearing choices to fit a wide array of riding styles and needs. Every feature, from accurate and reliable power measurement to new shift points, helps create an effortless experience so your energy goes into your ride.

Perfect fit

We’ve achieved new breakthroughs for brake hood comfort and fit with RED. Not just the perfect shape for any size palms, RED brakes also offer a wider range of independent reach and pad contact adjustment, and no pinching of fingers or bottoming out on the bar.

Effortless braking

One-finger braking from anywhere, with less effort. RED brakes require 80% less effort than before when braking from the hoods, and 33% less effort from the drops. More power, less hand fatigue.

Faster, more accurate shifting

A slimmer cage for fast and reliable front shifts, auto-trim to prevent noise, and easier setup than ever.

The right gear for you

Because everyone has different needs, we offer more cassette and chainring combos, so you can pick what works for you. And X-Range helps you shift less and stay in the big ring more.

Intuitive, instant, and always wireless

Fewer buttons, less to think about. With eTap shift logic, simply press the right button to go harder, the left to go easier. Hit both to shift the front derailleur.

Effortless setup with Hammerhead Karoo

Instant setup without pairing. Control configuration without pulling out your phone.

Shift or swipe without lifting a finger

With the Bonus Button, you can shift from a second location or control an ANT+ head unit. Your choice.

Personalize with AXS

Customize your shifting, analyze your gear usage, and confirm your bike’s readiness, all with AXS connectivity.

Lighter than ever

We didn’t just improve features. RED AXS is also the lightest electronic group you can get, 150 grams lighter than the previous generation.

Quiet and smooth, even when it’s rough

The Orbit damper in the RED AXS rear derailleur keeps tension on the chain no matter how bumpy it gets, and fits every cassette size from 10-28 to 10-36.

Effortless measurement, supreme accuracy

You can’t afford bad data. Our lightest, stiffest, and most accurate power meter won’t let you down.

Driven by Innovation Since 1987

SRAM was founded on a simple idea: there had to be a better way to shift. That belief led to the invention of Grip Shift and sparked a company built on challenging convention and rethinking how bikes work. From pioneering drivetrain systems and wireless electronic shifting to redefining mountain and road performance with 1x technology and AXS connectivity, SRAM has consistently pushed cycling forward. Through a growing family of iconic brands and rider-driven innovation, SRAM continues to shape the future of how the world rides.
