How fast? How far? How many RPM? Cannondale's IQ400 wireless computer has all the answers. Perfect for the data-hungry cyclist, this 18-function cyclo-computer offers an easy-to-read display of speed (current, average, and maximum), cadence (current, average, and maximum), odometer and trip distance. You'll also appreciate the auto on/off, trip and 12/24-hour clocks, a calorie-consumption estimator, temperature, low-battery indicator and backlight.
