Garmin Vector Powermeter Pedals One Color, 38mm Crank Width
You've been waiting for years, drooling and poring over discreet photos of Team Garmin Sharp prototypes at every race in the world. Yes, for more than three seasons, we've been guilty of this too. However, the wait is finally over, as the Garmin Vector Powermeter Pedals have arrived to market. And believe us -- it was worth the wait. So, let's tackle how this system actually works. To do this, we'll first examine how a "typical" powermeter operates. Essentially, there are normally a series of "strain gauges," either at the hub or crankarm spider. These gauges are actually a system of sensors that detect resistance and vary their output when experiencing applied force. Then, the aforementioned data is converted to electrical resistance, of which it's able to be measured and transmitted to your CPU. The Garmin Vector system, however, operates in a more mathematical sense. Garmin has created small sensors that fit inside the hollow spindles of each pedal. And holding these sensors in place are what Garmin calls "pedal pods." Basically, these pods are the guts of the system -- housing the sensor, ANT+ transmitter, and battery. On one side of the crankarm, the pedal passes through the pod into the threaded connection of the crankarm. This action secures the pedal pod in place, leaving the "sensor end" of the pedal pod to connect into the spindle -- don't worry, this process is incredibly simple. Once in place, the sensor is able to measure power from the most logical place -- at the pedal, where power is directly applied. It does this by measuring any deflection of the pedal when force is applied. From there, the sensor calculates the applied force vectors, calculating them in terms of power, and then transmitting the corresponding reading to your CPU via ANT+ wireless technology. And if your physics skills are feeling a little weary, a vector is basically just a quantity that has both direction and magnitude. With this in mind, you'll be happy to learn that this techn..
