SRAM Red 1 AXS™ Power meter

In certain disciplines, the single-ring drivetrain reigns supreme. Championing simplicity, strength and durability, the SRAM RED 1 AXS™ power meter meets the demands of triathletes, time trialists and cyclocross racers. The power meter features improved aerodynamics thanks to direct mount aero chainrings with fully integrated power, and the tighter gearing range is perfect for racing and flatter terrains.


  • Single-ring drivetrain simplifies functionality
  • 48 and 50t variants have fully integrated power into a direct mount aero chainring
  • 36-46t variants have spider-based power
  • 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
  • Power balance measures left and right legs separately
  • SRAM X-SYNC™ wide-tooth, narrow-tooth chainring technology provides maximum chain control
  • Laser-etched chainring finish is more durable
  • DUB™ bottom bracket adds durability and simplicity
  • Non-aero chainrings can be installed with a single tool, making gearing changes a breeze

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.

Quarq’s next-generation DZero™ power meter platform is named for the DØ Experiment, one of science’s most accurate and innovative projects to detect subatomic particles moving at the speed of light.

With a new measurement circuit, a revised strain gauge design, improved accuracy throughout the pedal stroke, and software advances, DZero™ represents the state of the art in power meter technology.

SRAM X-Sync™ 1x chainrings provide the highest level of performance and durability. The SRAM X-Sync™ tall sqaure teeth edges engage the chain earlier than traditional tirangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync™ chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in germany, X-Sync™ rings are an integral part of the SRAM 1x™ drivetrain. Accept no imitation.

Carbon Tuned™
Strength and stiffness where you need it, lightweight like you want it. Proprietary SRAM carbon lay-up design increases thickness and stiffness at critical stress areas. Tapered, terraced, carbon architecture ensures the greatest weight savings without compromising strength.

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.
