SRAM Rival AXS Left Crank Arm Power Meter Spindle Assembly - 172.5mm 12/13-Speed DUB PM Spindle BLK E1

Power data can transform your training, but adding a meter used to mean extra hardware and complexity. The Rival AXS left crank arm encases a spindle-based power meter that reads your left-leg watts and translates them into actionable performance metrics, all inside a clean, integration-friendly package for SRAM DUB setups.

Designed for cyclists who want precise power insight without compromising pedal feel or bike balance, this solution keeps weight low and installation straightforward, so you can train harder and race smarter.

Who is this for?

Ideal for riders who want objective power data with a minimal, integrated footprint—road racers chasing steady watts, triathletes balancing power with aerodynamics, and mountain bikers needing reliable metrics without adding clutter to the cockpit.
