Independent left and right measurement happens through sealed spindles that capture power from both legs simultaneously. This reveals asymmetries where one leg produces more force than the other, and it tracks changes across training blocks or after bike fit adjustments. The dual-sensing configuration measures both legs rather than doubling single-leg data, which provides actual left-right balance percentages. Advanced cycling dynamics include platform center offset, power phase, seated versus standing time, and force data that shows how power output responds to cadence changes.

The internal rechargeable lithium battery delivers 90 hours of ride time per charge, and the quick-charge function provides 12 hours of operation from 15 minutes connected to USB-C power. Two magnetic charging clips attach to contacts on each spindle without requiring disassembly. Travel mode puts the pedals into sleep state during transport to prevent battery drain. Battery status displays on paired Garmin Edge cycling computers and through the Garmin Connect mobile application.

Pedal IQ smart calibration monitors temperature changes, elapsed time since last calibration, and whether the pedals have been moved between bikes. The system alerts through connected Garmin devices when recalibration would improve accuracy. Manual calibration requires the pedals to be unweighted with cranks horizontal, which takes approximately 30 seconds. The calibration applies to the spindles regardless of which pedal body type you're currently using.

The RS road bodies provide a large platform that distributes force across the shoe sole, and the Shimano SPD-SL interface offers secure cleat engagement. The carbon polymer construction reduces weight while maintaining stiffness under hard pedaling efforts. The XC off-road bodies feature an 11.5mm stack height that sits 2mm lower than previous XC generations, which reduces pedal strike risk on technical terrain. The all-metal construction withstands repeated impacts from rocks and roots, and the open SPD engagement mechanism self-clears mud automatically. Both pedal body types use sealed cartridge bearings that resist contamination.

The system broadcasts on both ANT+ and Bluetooth protocols, providing compatibility with Garmin Edge cycling computers, watches, and third-party head units. The data integrates with training platforms including TrainingPeaks, Strava, TrainerRoad, and Zwift. The pedals work with oval chainrings without requiring special calibration modes. Spring tension on both pedal body types adjusts with a 3mm hex key to customize entry and release force. The 53mm Q-factor matches most road and mountain bike cranks, with optional spacer washers available to increase to 55mm if needed.
