Sram Rival Wide Axs Dub Direct Mount With Power Meter

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.Features:- An elegant integrated design- DUB-PWR spindle-based unit measures left side power to calculate total watts- Proven Quarq reliability and accuracy- Long battery life (400+ hours) to power a season of rides- User replaceable lithium AAA battery- DUB bottom bracket adds durability and simplicity- Waterproof (IPX7 waterproof to 1 meter for 30 minutes)- Lightweight (less than 40g heavier than standard crankset)- Wide chainline crankset for bikes with the widest gravel tiresSpecifications:- CRANK ARM Length: 165mm- Bb Spindle Interface: Dub- Bb Compatibility: All Sram Road Wide Dub Bbs- Speeds: 12- Chainring Material: Aluminum- Bolt Circle Diameter (Bcd): Direct Mount (Dm)- Chainline: 47.5mm- Chainring Size: 40t- Standard: 142mmTechnology: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.DUB:- 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 developinga complete system that equals better drivetrain performance.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. We 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.
