SRAM RED AXS Power Meter Spider

The SRAM RED AXS Power Meter Spider uses Quarq’s premier DZero power measurement technology which promises accurate and consistent power readings regardless of the climate or conditions. This power meter also features dual ANT+ and Bluetooth SMART, left and right power balance and a full 2-year warranty.


Key Product Details


This power meter is compatible with SRAM RED AXS 8-bolt DUB and GXP cranksets. See Compatibility tab for more information.

Power Measurement:

The SRAM power meter measures power at the spider and is therefore able to measure power from both legs.

Key Features:

Dual-leg power measurement, integrated 1-piece chainrings, accurate to +/- 1.5%, CR2032 user-replaceable battery, left/right power balance, ANT+ and Bluetooth compatibility, auto-zero (automatic calibration). See Specs tab for more information.

Advice From Our Staff:

This is SRAM’s nicest, but also most expensive, 2x road power meter spider. It features a 1-piece fully integrated power meter spider and chainrings, which makes it lightweight and stiff. We also like that the power meter measures power from both legs as well as provides left vs. right power balance. One thing to note – while the RED chainrings are made to last 50% longer than SRAM’s 11-speed chainrings – the chainrings cannot be replaced when worn, since the rings and power meter are one solid piece. Most customers however can get many years of life out of the power meter before it needs to be replaced.


Options For This Power Meter

Chainrings: The power meter is available in the following chainring sizes:

  • 46/33 | 48/35 | 50/37


Other Versions to Consider

Complete RED Crankset: If you would like to purchase the power meter plus crankarms, we have the SRAM RED AXS Power Meter Crankset.

1x AXS Version: We also sell the SRAM RED 1x AXS Power Meter Spider which features a 1x aero chainring.

Force AXS Version: We also sell the SRAM Force AXS Power Meter Spider. The Force version is more affordable than the RED version on this page.


Cranks: This power meter is compatible with SRAM RED AXS 8-bolt DUB and GXP cranksets.

Bottom bracket: Compatible with SRAM DUB or GXP bottom brackets (based on the crankset version).
