Effortless Performance. Effortless Perfection

You want your performance to represent 100% of what you put in, and SRAM designed RED AXS with that goal. RED AXS is not just the SRAM’s lightest electronic groupset ever, it has more comfortable and lower-effort braking, more precise shifting, and expanded gearing choices.

Riding isn’t effortless SRAM RED is.

Intuitive, Instant Wireless Shift Logic

SRAM continues to lead the way in their shift logic. Right is harder, left is easier, push both to operate the front derailleur. It’s one of SRAM’s most popular product features across the Road AXS product. Plus, this AXS enabled lever provides easy setup, personalization, and reliability.

Shift or Swipe Without Lifting a Finger

Bonus Button lets you shift or control ANT+ devices with your thumbs. Out of the box, Bonus Button comes as a standard shifter, however, it can easily be programmed to do other functions through the AXS app.

Faster, More Precise Front Shifting

Not just fast and reliable front shifts, but silent running across the whole cassette. The RED AXS front derailleur has a refined shape and uses Yaw technology with electronic trim to ensure the fastest possible shift while eliminating chain rub in all combinations. And with a brilliant new tool, the easiest setup around.

Heart of the AXS Ecosystem

The RED derailleur is now lighter, more efficient, and more capable than ever. Covering cassette ranges from 10-28T up to 10-36T, this wireless wonder has larger pulleys to decrease chain articulation and increase efficiency, and an Orbit fluid damper to keep everything in place over the rough stuff. One derailleur ready for 1x or 2x, on road or off.
