SRAM Red/Force AXS Power Meter Spider

The SRAM RED/Force AXS 107 BCD Power Meter Spider is the upgrade path for SRAM RED/Force eTap AXS cranksets, accurate to within ±1.5% and providing both left and right leg power data through SRAM's AXS electronic integration platform. If you already own a Red or Force AXS crankset and want power data without buying a whole new drivetrain, this is the drop-in path — you swap the non-power spider for this one, keep your crank arms and DUB spindle, and end up with a spider-based Quarq powermeter running on the AXS ecosystem.

Power measurement happens at the spider, which means it measures power from both legs rather than doubling a single-leg reading. That matters if you care about left/right balance data during training, or if you've ever been skeptical of single-sided meters that estimate total output. The IPX7 waterproof rating and 10k temperature compensation handle 200 hours of ride time in any weather condition, so accuracy holds up through wet fall training and cold winter base miles without drift.

Compatibility is the piece to get right before ordering. Power-upgrade compatible with RED and Force eTap AXS cranksets: RED 1x from 36T to 46T, Force 1x from 36T to 46T, and Force 2x in 33/46T and 35/48T configurations. The spider uses a 107 BCD 8-bolt interface and requires SRAM AXS 107 BCD chainrings (sold separately). If you're running the newer one-piece integrated Red AXS powermeter chainrings or the thread-mount XPLR spider, this is not that product — this is the traditional D1 spider that accepts bolt-on chainrings....
