SRAM Rival 172.5mm Left Arm / Power Meter Spindle, D1 DUB Wide 172.5, D1 DUB Wide 172.5 (Right Arm/BB/Spider/Chainrings not included)

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.

Technology

AXS

AXS is SRAM's new bike component integration system connecting electronic bicycle components and software. The SRAM AXS app allows riders to see battery status, change component behavior, personalize controls, and get maintenance reminders, and update firmware.

DUB

The relationship between the 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 the approach to developing a complete system that equals better drivetrain performance.

DUB-PWR

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.
