reliably. The speed reading comes and goes. I've tried sensor adjustments, resets, battery changes, changing wireless channels (as well as tech support call to Cateye, said do the above). Speed is sometimes there, sometimes 0. It comes and goes during a ride.
Before deciding this is a replacement situation, probably only the sensor assembly, I thought I'd ask if anyone had found a fix for this if they experienced it.
Sensor position is spot on.
