Spider-based power meter
SRAM Force AXS E1 Thread Mount Power Meter Spider
A dual-sided power meter spider for Force E1 cranks that takes SRAM's Thread Mount chainrings, so you can add power or change ratios without replacing the whole chainset.
Highlights
Why we rate it
Measures both legs
Strain gauges in the spider read total power from both sides, along with left/right balance.
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.
