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.
