Power Measurement

This Rival power meter measures left leg power. It then doubles the value to account for both legs (assumes both legs are generating the same force).

Compatibility

This power meter is compatible with SRAM Rival E1 road cranksets. It uses a standard DUB spindle that is compatible with most road bikes. See Compatibility tab for more information.

Considerations

This is a left-side only power meter, so it estimates total power by doubling the left leg’s output which can be less precise than dual-sided options. For riders who want to ensure they have the most accurate data possible, we would recommend considering a dual-sided power meter.
