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.
This power meter is compatible with SRAM RED AXS 8-bolt DUB and GXP cranksets. See Compatibility tab for more information.
The SRAM power meter measures power at the spider and is therefore able to measure power from both legs.
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.
