SRAM AXS Powermeter Spider

The SRAM AXS Powermeter Spider is the most efficient way to add power measurement to an existing SRAM Red or Force AXS crankset. Rather than replacing your crank arms or pedals, it swaps directly into the 107mm BCD spider position on compatible DUB spindle cranks — keeping your current setup intact while adding the data infrastructure of a Quarq DZero DUB power meter.

Accuracy is ±1.5%, and unlike some power meters that drift in extreme heat or cold, this one uses a 10,000-point temperature compensation system to maintain consistent readings across a full range of conditions. IPX7 waterproofing handles rain without issue. Whether you're training in July heat or wet fall weather, the numbers stay reliable. That kind of environmental resilience matters for riders who don't stop when conditions get difficult.

The AXS integration is a practical differentiator. The powermeter connects to the SRAM AXS app over Bluetooth Low Energy, allowing you to check battery status, update firmware, and manage settings directly from your phone. ANT+ keeps it compatible with virtually every head unit on the market. The CR2032 battery lasts approximately 200 hours of ride time and swaps without tools — no coin required, just a quick press-and-turn on the battery door.

Chainring compatibility covers the full range of current Red and Force AXS configurations: Red AXS 1x (36T–46T), Force AXS 1x (36T–46T), and Force AXS 2x (33/46 and 35/48). If you're running any of these combinations, the powermeter spider drops in without modifying anything else on your drivetrain.
