New Features

  • A simplified product line – choose a power meter spider and preferred crank arm length

DZero is packed with 10 years of technical innovations and 150 documented technology iterations. Now combined with SRAM’s DUB™ technology – stronger, stiffer, lighter.

The Heart Of Your Bicycle

The sole job of the crankset is to convert the effort from both legs to forward motion. It is the perfect place to measure power.

Designed To Make You Faster

Quarq’s direct force power meters measure what wins races — total power output from both legs — with 1.5% accuracy.

Built To Last

All power meters have an IPX7 waterproof rating. They feature a 2-year warranty, free firmware updates and acclaimed worldwide support.

Simplified Products. Simplified Use.

With MagicZero™ - automatic calibration as you ride - you no longer need to backpedal or manually calibrate your headunit.

10K Temperature Compensation

Each power meter is programmed with over 10,000 data points to eliminate temperature effects on power measurement.

A Companion Digital Wrench

With the SRAM AXS app you can set the zero offset, check battery voltage, run diagnostics and perform firmware updates.
