Product Details

Key Features of the Rival E1 XPLR Power Meter Crank Arm

• Easy to Upgrade: Simply replace your left crank arm for +/- 1.% accurate power measurement.
• AXS Compatible: Wirelessly pairs with the SRAM AXS App for setup and firmware updates.
• DUB Wide Spindle: Specifically designed for gravel and adventure bikes.
• Replaceable AAA Battery: Up to 400 hours of battery life with no charging needed.

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 gravel cranksets. It uses a standard DUB Wide spindle that is compatible with most gravel 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 gravel riders who want to ensure they have the most accurate data possible, we would recommend considering a dual-sided power meter.

Advice From Our Staff:

We believe this crank arm is ideal for gravel and adventure riders who already have a Rival E1 XPLR crankset. This is one of the easiest and most affordable ways to get into power‑based training. The PMC staff recommends it for recreational and serious riders who want accurate data without the high cost of dual‑side power meters.
