AXS is SRAM’s new bike component integration system that connects electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, get maintenance reminders, and update firmware.
DUB-PWR takes Quarq’s reliable and accurate power measurement and elegantly houses it inside the DUB crank spindle for compatibility with any chainring setup, measuring left side power to calculate total watts. It’s lightweight, invisible and attainable.
