Top 5 – Power Meters For Your Road Bike

With so many power meters available on the market, it can be hard to decide which one is best for you. The number of power meter manufacturers is continually increasing, with many of them offering a range of designs. From single-side and dual-side cranks to pedal and hub-based systems. All of them are designed to do the same thing; measure the power output of a rider and transmit it to a head unit to help you gauge and improve your performance on the bike. The difference between each of them lies in accuracy, affordability and compatibility.

    PowerPod Powermeter V2

    The PowerPod measures, up to 800 times per second, the opposing forces caused by hills, wind, acceleration, and friction. Opposing forces matched identically by the forces applied by both legs, determine the cyclist’s power. The unit is attached to the handlebars meaning you can use any cranks, wheels or pedals and the device can quickly be switched between bikes.

    According to PowerPod, the V2’s accuracy is on a par with dual-sided crank-based systems and is superior to single-sided power meters. At less than £300 it’s an affordable solution to training with power if you have a limited budget.
