Power meter
SRAM Rival AXS E1 Power Meter
The 2025 Rival 2x crankset with a spindle-based power meter that measures the left leg and doubles it for total power. It runs on a single user-replaceable AAA lithium battery for 400+ hours and adds less than 40 g over the standard crank, making it the cheapest way into SRAM-integrated power.
Fitted to 18 builds across 10 bikes in the database.
