Cycling dynamics data will be sent to head units that support the collection and display of this new information from a Vector dual sensing system. (Note. Vector S will not send cycling dynamics data unless it is upgraded to a dual sensing system)
In this first release of cycling dynamics the following information has been added.
Add calculation and output of Cycling Dynamics, Power Phase. Add calculation and output of Cycling Dynamics, Peak Power Phase. Add calculation and output of Cycling Dynamics, Platform Center Offset (PCO).
This release is available via the use of the Vector Updater.
In order to collect and view cycling dynamics data you will need a cycling computer (head unit) that supports it. The units that currently support cycling dynamics are the:-
Edge 1000 software build 2.70 or higher Edge 810 software build 3.40 or higher Edge 510 software build 3.40 or higher
These 3 Edge software builds are being released on 2014-12-30 and can be obtained using Garmin Express or the Web updater.
Power Phase - This is the period in the crank rotation when you are producing power (positive torque). It is reported for both the left and right sides using a start and end angle.
Peak Power Phase - This is the angular range where you are producing a specified fraction of the total power for a crank rotation. It is reported for both the left and right sides using a start and end angle. By default the fraction is set to 50%. This peak power fraction setting can currently be adjusted via the Edge 1000 if desired.
Platform Center Offset (PCO) - This is where on the pedal platform the force is being applied and is reported for both the left and right sides. The center of the pedal platform is zero (0). Forces applied inboard of the center line are reported as negative, while those that occur outboard of the center line are reported as positive. The PCO is reported in millimeters.
Coordinate system - The angular data reported by cycling dynamics uses the following reference points
Top Dead Center (TDC) is zero (0) degrees Crank forward and horizontal, 3 o'clock position, is 90 degrees Bottom Dead Center (BDC) is 180 degrees Crank rear horizontal, 9 o'clock position, is 270 degrees.
