SRAM Rival AXS E1 Power Meter Crankset - 170mm, 48/35T

The SRAM Rival AXS E1 Power Meter Crankset combines a 2x12-speed road crankset with power measurement integrated directly into the DUB spindle.

This configuration uses 170mm aluminum crank arms and 48/35T X-Range chainrings, delivering race-ready road gearing with integrated training data in a clean, lightweight package.

DUB Spindle Power Meter

The Rival AXS power meter is housed inside the DUB spindle and measures power from the left side to calculate total wattage.

The system connects through ANT+ and Bluetooth, making it compatible with supported cycling computers and training devices.

A user-replaceable lithium AAA battery provides 400+ hours of battery life, while IPX7 water resistance helps protect the power meter in wet riding conditions.

The power meter adds less than 40g compared with the standard Rival crankset.

Bottom bracket is not included.
