Description

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.

Features

  • 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
  • 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

Technical Features

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 developing a complete system 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.
