Power-Based Cycling

Tech & Tests

Training and racing with a power meter means being able to monitor your performance with real hard data – not estimates. Power is an objective and reliable reference value that, unlike heart rate, can not be altered by external factors such as high temperatures, psychological stress, caffeine intake, digestion, etc.

As a matter of fact, there is a direct causal relationship between the power generated on the pedals and the speed achieved by the cyclist.

the higher the power = the better the performance

known and exploited in professional cycling for decades now, the power-based training principles have only recently become accessible to amateur cyclists too: thanks to a new generation of reliable and accurate cycling power meters.

What is power?

Power is a physical magnitude that indicates the workload accomplished by a force within a given period of time.

Power = Work / Time

The units of power, time and work are respectively: watt (W); Second (s) and Joule (J).

1 W = 1 J / 1 s

In cycling...

To advance on a bike you have to generate mechanical power at the level of the crankset: this power is simply the product of the force with which you push the pedals (torque) and the speed of your pedaling (cadence).

Power = torque* cadence

So, to get faster on a bike you need to produce more power; to produce more power you need to exert more force on the pedals or increase the pealing pace (or, of course, do both at once).

Real Dual-Sided Power Measurement

Favero Electronics bike power meters measure the power hundreds of times per second and continuously transmit the collected data to your bike computer or smartphone via Bluetooth and ANT + technology.

You can see the power data (watts) on your mobile device anytime, with the view option you prefer.

Plus, the Assioma power sensors are placed on the pedals, exactly where the cyclist’s force is applied. This ensures an accurate data collection not only of the total power but also of the L/R power balance, the Torque Efficiency, the Pedal Smoothness, etc.
