MyChron Rear Wheel Speed Sensor
The wheel speed sensor picks up your MPH (mile per hour).
This receiver is compatible with the My Chron 3 Plus/Gold, MyChron4, MyChron5, and My Chron E-Box.
You will also need to purchase a magnetic axle collar in order for this sensor to pick up a reading. If you already have axle collars we also carry screw in magnets that can be tapped into your collar.
