SRAM RED E1 AXS Power Meter Spider

The SRAM RED E1 AXS Power Meter Spider uses Quarq’s premier DZero power measurement technology to provide accurate and consistent power readings. It is +/- 1.5% accurate and has active temperature compensation to make sure temperature changes don’t affect your power numbers. This power meter uses integrated chainrings to save weight and improve shifting performance. It 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 2x 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 premier 2x road power meter spider. The chainrings are fully integrated into the power meter which improves shifting while also making it lightweight and stiff. This power meter also measures power from both legs and provides left vs. right power balance. 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 piece. Most customers can get many years of life out of the power meter before it needs to be replaced and SRAM offers a 50% off replacement when needed.


Options For This Power Meter

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

  • 46/33T | 48/35T | 50/37T | 52/39T | 54/41T | 56/43T


Other Versions to Consider

Complete RED Crankset: If you are looking for a complete power meter crankset with crank arms, we recommend the SRAM RED AXS E1 Power Meter Crankset.

RED 1x AXS Spider: We also sell the SRAM RED 1x AXS E1 Power Meter Spider which features a 1x aero chainring.

Force AXS Version: For riders looking for a more affordable power meter, we recommend the SRAM Force AXS Power Meter Spider. This power meter spider still uses the same integrated chainrings and is just as accurate, but is more affordable.
