Technology
At the heart of Vector is a custom-designed system with over 60 piezoresistive strain gauges, accelerometers, and temperature sensors and an efficient electronics architecture that processes the forces that a cyclist applies to the pedals. The sensors and electronics are environmentally sealed within the pedal spindle and each unit is calibrated by MetriGear.
By detecting the microstrain that naturally occurs in the spindle as the cyclist pedals the bicycle, Vector uniquely measures force vectors – the magnitude and direction of the cyclist’s pedaling effort. Vector measures these forces independently in each leg throughout the entire pedal stroke, collecting data at a rate of more than half a million samples per second. “Productive” force, “waste” force, the extent to which the cyclist pulls up, pulls across the top, pushes down, etc., Vector measures and collects it all.
Vector Features
- Precise force measurement system implemented into the hole in each pedal spindle
- Implemented in stock pedals, requiring no modifications to pedal platform or spindle
- Independently measures forces in each leg, and reports total power (watts)
- Sensors and electronics are environmentally sealed inside pedal spindle
- Transferable between bikes – swap pedals and attach battery packs to cranks
- Accuracy of +/- 1.5% of actual force on pedals
- System precisely measures cadence, cadence sensor or magnet not required
- Less than 50 grams of total incremental weight (less than 25 grams/pedal)
- Communicates via ANT+ wireless protocol to ANT+ compatible head units
- Includes ANT+ PC dongle for Vector firmware updates/upgrades as available
- External rechargeable battery pack securely mounts on crank, with a charge indicator on the battery pack
