Power Tap

Power Tap Zipp Power Tap

Power Tap is a state-of-the-art training system that allows you to measure in real time the intensity of the work you are doing on the bike. Unlike heart rate, the measurement of power is not effected by environmental or biological factors like heat, humidity, fatigue, stress, dehydration, altitude or illness. Power (measured in watts) is the purest measure of the work you are doing and therefore is the most accurate method of regulating intensity every time you train or compete.

The Power Tap system consists of three components: the Power Tap hub, receiver, and CPU.

The Power Tap hub senses torque inside the hub at a rate of 60 times per second. Torque and wheel speed are used to calculate instantaneous power. The torque sensor data is transmitted via a wireless connection to the seatstay mounted receiver. The hub is completely serviceable without disturbing the torque sensing strain gauges and associated electronics under the plastic cover.

The Power Tap receiver mounts to the seat stay and receives torque data every second via a digital wireless signal. The torque data is continuously sent to the handlebar mounted CPU via a 4-conductor wire. The mounting shoe, which is securely clamped to the handlebar, accepts the Power-Tap computer in a slide-in snap fit. The receiver features tough wire sheathing and ultrasonic welded plastic housings to shield it from the elements.

The computer can store up to 9 discrete non-overlapping intervals. At any time after you've recorded an interval, you can review all of the average and maximum values (power, heart rate, speed, and cadence) as well as the accumulated values (distance, time, and energy expenditure). It stores up to 7+ hours of ride data for subsequent downloading to a PC. The user interface is logically planned and is surprisingly easy to use considering the amount of embedded features. The computer housings are ultrasonically welded together and the O-ring on the battery door and the hermetically sealed interface buttons make it very water resistant.
