Measures both legs
Strain gauges in the spider read total power from both sides, along with left/right balance.
Spider-based power meter
SRAM Force AXS E1 Thread Mount Power Meter Spider

Highlights
Why we rate it
Thread-on chainrings
Rings screw onto the spider rather than bolting on, keeping it light and stiff while still letting you swap ratios.
Looks after itself
MagicZero checks and recalibrates during rides, temperature compensation is built in and no cadence magnet is needed.
Easy battery swaps
Runs on a standard CR2032 coin cell you can change yourself; battery status and firmware are handled in the SRAM AXS app.
