Sram Red AXS Quarq Power Meter DUB 2x12S 48-35 crankset
Welcome to the pinnacle of the power meter!
The Sram Red AXS™ power meter breaks with tradition and brings you to a new level of performance. The power meters are designed with Quarq’s premier DZero™ power measurement technology fully integrated into the chainring with a "direct mount" mounting system, in order to fit perfectly with the new Sram Red Dub crankarm.
Features

- Chainrings can be easily changed without requiring recalibration of the power meter.
- Power readings are accurate within +/-1.5% and aren’t affected by climate conditions during a ride.
- DUB™ bottom bracket adds durability, simplicity and broad compatibility.
- Laser-etched chainring finish is more durable.
- Speeds: 12
- Bottom Bracket Compatibility: all Sram Road DUB™ BBs.
- Bolt Circle Diameter (BCD): Direct Mount.
- Chainline: 45.0 mm.
- Chainring Material: aluminium.
- Crank arm length: 170mm, 172.5mm, 175mm.
Technologies
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.
AXS™
AXS™ is Sram’s new electronic integration platform 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. Sram took it a step beyond conventional thinking and made everything simpler — and better integrating the relationship between chainring, crank, spindle and bottom bracket. It’s this clear system approach that equals better drivetrain performance.
DZero
Quarq’s next-generation DZero power meter platform is named for the D0 Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light.
Exogram
The Hollow Carbon Construction starts in the crank arm and extends into the crank’s spider, maximizing the stiffness to weight ratio.
