Sram Power Meter AXS crankset
The SRAM RED AXS power meter breaks with tradition and reaches new levels of performance. We have redesigned the road gearbox: reducing the size of the front chainring and adding more autonomy to the rear cassette. We've also maintained a 13-tooth delta across all chainring pairs, ensuring precise shifting for any setup. This results in more useful gears and better shifts in all configurations. Designed with Quarq DZero power measurement integrated into the crankset. Welcome to the pinnacle of power metering.
- X-Range shifting technology gives you greater range and smoother gear progression, so you're always in the right gear
- The power meter is fully integrated into the chainring set for lighter weight
- Power readings are accurate within +/- 1.5% and are not affected by weather conditions while riding
- Measures the power balance of the right and left leg
- Improved front shift performance for crisp, precise front shifts
- The unique crown shape results in a lighter, stiffer and more durable crankset
- The integrated crown design significantly reduces weight
- The DUB bottom bracket adds durability, simplicity and broad compatibility
Technology
DUB
The relationship between the bottom bracket pivot and the bearing is at the heart of DUB technology. It's where rigidity meets durability. We've taken a step beyond conventional thinking and made everything simpler by better integrating the relationship between chainring, crank, spindle and bottom bracket. It is this approach to developing a complete system that equates to improved powertrain performance.
DZero
Quarq's next-generation DZero power meter platform is named after the D0 experiment, one of the most accurate and innovative scientific projects to detect subatomic particles moving at the speed of light.
X-Range
Road bikes are faster and more capable than ever, and cyclists are expanding what's possible with drop-bar bikes. X-Range is preparing for today's street driving. We've completely reinvented the street shifter for wider range, more useful and smoother gear progression, as well as smarter shift settings, made possible by AXS. With X-Range you are always in the right gear.
Exogram
Our hollow carbon construction starts in the crank and extends into the crank spider, maximizing the stiffness-to-weight ratio.
AXS
AXS is SRAM's new bicycle component integration system that connects bicycle electronics and software. The SRAM AXS app allows riders to view battery status, change component behavior, customize controls, receive maintenance reminders and update firmware.
