A power meter measures your power output and is measured as a calculation of torque (how hard you’re pushing the pedals) multiplied by cadence (how fast the pedals are turning). Your power is measured in watts which gives you a precise calculation of how much energy you’re putting through the pedals at any given moment. With this knowledge, you can calculate your training load, target precise effort levels through your training zones, track improvements in your fitness, determine how many calories you’re burning etc. Power meters come in all shapes and sizes including a pedal power meter and crank power meter. There are a number of high quality brands that cyclists use which include SRAM Quarq power meter, Stages Shimano power meter , Favero Assioma Duo power meter.
