True one-finger braking is at hand. SRAM has overhauled their 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 they still managed to remove 83g from the pair.

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.
