SRAM completely overhauls 12-Speed RED AXS: "Refined to create an effortless ride"

sram red axs 12 speed 2024 review — SRAM Red AXS has been completely overhauled

Every part of RED has been refined to create an effortless ride. Light brake feel and comfortable ergonomics, smooth front shifting, fully wireless connectivity, and expanded gearing choices fit every rider and their needs. RED is packed with features, like accurate and reliable power measurement, new shift points, and more brake adjustability, while still shaving grams off every component to bring you the lightest electronic groupset ever. Riding isn’t effortless. RED is.” – SRAM

RED AXS HRD Shift-Brake System

“True one-finger braking is at hand. We’ve overhauled our hood and lever architecture and achieved breakthroughs for fit across all hand sizes and easy access to powerful and smooth, easy braking from anywhere on the bar. Independent reach and contact point adjustment allow for highly personalized setup, with no risk of pinching your fingers or bottoming out on the bar no matter your settings. Better finger wrap on the hood means less fatigue on long days, and Bonus Buttons lets you shift or control ANT+ devices with your thumbs. The caliper is not only stiffer, but lighter too, with phenomenal pad clearance for rub-free operation. All that and we still managed to remove 83 g from the pair.”

Features:

One finger braking from the hoods or the drops
83 g lighter than previous generation
AXS enabled for easy setup, personalization, and reliability
eTap shift logic for intuitive shifting
Bonus Button provides ANT+ device control or auxiliary shift option
Optimized hood shape fits the widest range of hand sizes
Carbon brake lever for light weight
Textured shift paddles and hoods for control and comfort
Bleeding Edge technology for easy and clean bleeds
Reach Adjust to personalize fit for more hand sizes
Contact Point Adjust to personalize brake engagement
