Cycling Dynamics
With a dual-sensing, pedal-based power meter system such as the Rally 210 pedals, you can access advanced
training data known as cycling dynamics. Cycling dynamics can give you detailed insights into how you are
applying power to the pedals, and how your performance changes based on position, bike setup, ride duration,
and more.
Right/Left Balance: Tracks the percentage of total power applied to each pedal.
Power Phase: Tracks the start and end of the power phase (the part of your pedal stroke in which you generate
positive power).
Seated/Standing Position: Tracks your riding position throughout the ride.
Platform Center Offset: Tracks how force is distributed across the pedal platform during the pedal stroke,
measured in millimeters from the center line of the pedal platform.
You can view cycling dynamics in data fields on your compatible Edge
®
device during your ride (Data Fields,
page16). After you save and sync your ride, you can analyze cycling dynamics data on your Garmin Connect
account.
For more details on the cycling performance metrics supported by Garmin devices, go to garmin.com/garmin
-technology/cycling-science/.
14 Cycling Dynamics
Force Data
The Rally 110/210 pedals measure the amount of force you apply to the pedal platforms, measured in Newtons.
Force data can help you understand how various factors affect your ability to produce power. For example, you
can see how much force it takes to produce 300W at 60rpm compared to 100rpm.
You can view force data on your compatible Garmin device during your ride (Data Fields, page16). After you
save and sync your ride, you can analyze cycling dynamics data on your Garmin Connect account.
Pedal IQ
™
Smart Calibration
The Rally 110/210 pedals must be calibrated periodically to ensure the accuracy of power readings. By default,
