The SRAM RED AXS E1 Power Meter Spider DUB is SRAM’s lightest and most advanced power meter to date, built for road cyclists who demand absolute accuracy, efficiency, and race‑ready performance. Fully integrated into the chainring spider, this system delivers precise data without compromising weight, stiffness, or aerodynamics.

Available through leading Brisbane bike shops, the RED AXS E1 power meter spider is widely fitted during professional bike fitting, high‑end road bike builds, and premium bicycle servicing across Queensland.

Fully Integrated Spider‑Based Power Measurement

By integrating the power meter directly into the chainring spider, SRAM has reduced weight while improving accuracy and durability. This design measures total power at the crank, ensuring consistent data regardless of terrain, cadence, or riding style.

The system provides:

  • Accurate power measurement within ±1.5%
  • Reliable performance unaffected by temperature or weather changes
  • Left/right power balance data for detailed training analysis

This makes it an ideal choice for racers, endurance athletes, and data‑driven cyclists.

Notable Tech, Materials & Construction

Lighter, Stiffer E1 Carbon Crank Interface

The E1 generation features updated hollow carbon crankarms that are approximately 29 grams lighter than the previous version, without sacrificing stiffness. Improved stiffness translates directly to better power transfer, sharper acceleration, and a more connected road feel.

Combined with the integrated spider, this results in one of the lightest complete power‑meter crank systems available for performance road bikes.

Aero X‑SYNC Direct‑Mount Chainring Design

The power meter spider uses SRAM’s direct‑mount X‑SYNC chainring interface, delivering excellent drivetrain efficiency and longevity. The aerodynamic chainring profile reduces drag while maintaining crisp, reliable shifting under load.

This setup is ideal for modern 12‑speed SRAM AXS drivetrains and fast road riding where efficiency matters most.

DUB Spindle Platform for Reliability

The power meter spider is designed for use with SRAM DUB crankarms, providing a strong, durable spindle interface with simplified compatibility across modern road frames. The DUB system is widely supported during professional workshops and bike builds in Brisbane.

Bottom bracket not included; selection depends on frame standard.
