10K™ temperature compensation eliminates temperature effects on power measurement.
AxCad™ accelerometer cadence removes the need for a magnet.
An LED and visible ANT+™ ID streamline installation and operation.
OmniCal™ means you can change chainrings without affecting accuracy.
CR2032 battery – 300 hours of riding time
+/- 1.5% accuracy
