The Assioma PRO RS pedals are the lightest road power meters out there, tipping the scales at just 123.5g each! Made for Shimano® SPD-SL® cleats, they deliver pro-grade performance with over 60 hours of battery life—no interruptions. Thanks to a sealed power spindle that keeps all the electronics safe and separate from the pedal body, these pedals are tough and super easy to maintain. Their sleek design, low stack height, and narrow Q-factor help you boost your road training. With ±1% accuracy and a treasure trove of power data, plus a modular setup to swap between road and MTB bodies, these pedals let you train smart and ride fearless!
