A iBike iPro generation 3 wireless power meter. This has the GT firmware which makes it ANT+. It will read any ANT+ device - heart rate monitor, speed, cadence sensors, even Powertap and Quarq! It will also send power data to Garmin computers. I have found this to be no less accurate than a Powertap and is very repeatable, which is probably more important in my view.
Comes with the computer, wireless handlebar mount with extra battery for extended use, original box. It DOES NOT come with heart rate monitor, cadence or speed sensors.
