Power every ride. We’ve taken the reliability, elegance and features of Quarq’s legendary crank-based power meter and dropped the barrier to entry once again. This new power meter platform is entirely contained within the DUB spindle for clean integration that fits more bikes than ever. It’s invisible technology that adds minimal weight and will help you get to the finish line faster, and can be used to upgrade any eTap AXS bike to power.
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.
The relationship between bottom bracket spindle and bearing is the core of DUB technology. It’s where stiffness meets durability. We took it a step beyond conventional thinking and made everything simpler—better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this approach to developing a complete system that equals better drivetrain performance.
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.
