Pedal-Based Power
Vector measures pedal-based power.
EN
Vector measures the force you apply a few hundred times every second.
Vector also measures your cadence or rotational pedaling speed. By measur-
ing the force, the direction of force, the rotation of the crank arm, and time,
Vector can determine power (watts). Because Vector independently measures
left and right leg power, it reports your left-right power balance.
NOTE: The Vector S system does not provide left-right power balance.
Cycling Dynamics
Cycling dynamics metrics measure how you apply power throughout the
pedal stroke, and where you apply power on the pedal, allowing you to
understand your particular way of riding. Understanding how and where you
produce power allows you to train more efficiently and evaluate your bike fit.
Using Cycling Dynamics
Before you can use cycling dynamics, you must pair the Vector power meter
with your device (Pairing Your ANT+ Sensors, page 65) .
NOTE: Recording cycling dynamics uses additional device memory.
