Sorry about that, didn't mean the distance the wheel rolled but the  
vertical motion for studying the suspension performance. Thats what I  
meant about the telescopic tube using ultrasonic range finding to  
record the instantaneous length of said tube.

Already have a magnet on the front brake rotor with a reed relay  
pickup driving the speedometer/odometer.
