Hi at all, I have buyed a powertap 2.4 wireless speed / cadence sensor. I have installed a cadence sensor and work good but I have a problem to install this sensor as a speed sensor. I know that this sensor work only in one mode (speed or cadence), but the computer don't "see" the sensor.

Someone can say me how install step by step this speed sensor?

Thanks in advance.
