SRAM Rival AXS D1 Quarq Road DUB Power Meter Crankset 2x12-speed 46/33T black

Power on every ride. SRAM has taken the reliability, elegance and features of Quarq's legendary shaft-based powermeter and lowered the barrier to entry once again. This new powermeter platform is fully housed in the DUB shaft for a clean integration that fits more bikes than ever before. It's an invisible technology that adds minimal weight and helps you get to your destination faster. It means any eTap AXS bike can be retrofitted with power.

DUB technology
The crankshaft and bottom bracket assembly is at the heart of DUB technology. This is where stiffness meets durability. SRAM has gone a step further and made everything even simpler and better. It is the system approach through the integration of chainring, crank, shaft and bottom bracket that means better drivetrain performance.

AXS
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.

X-Range
Road bikes are faster and more capable than ever before, and riders are expanding what’s possible with drop bar bikes. X-Range is gearing for today’s road riding. SRAM completely reimagined road gearing for wider range, more useful and smoother gear progression, as well as smarter shift settings—enabled by AXS. With X-Range, you’re always in the right gear.
