Important Precautions: • Before beginning any exercise program, consult your physician. • Keep your eyes on the road. Do not become overly engaged with the PowerTap display. We recommend familiarizing yourself with computer functions while stationary. • The computer, chest strap, and hub are water resistant, not water proof. Avoid sustained water contact and do not deliberately place the PowerTap or its components in water or under high-pressure sprays.
Important Precautions, cont. • The PowerTap wheel does not include a quick release skewer. • Failure to adhere to these precautions may cause premature failure or incorrect operation of the unit and may void the warranty. Please register your PowerTap at www.cycleops.com. IMPORTANT: For your safety, the non-drive side of the PowerTap hub must be built with at least a 2x lacing pattern. Because of the patented PowerTap design, torque is transferred through the hub to the non-drive side.
System Overview THE POWERTAP SYSTEM The PowerTap system includes a power-measuring hub which measures torque and wheel speed. This information is transmitted to a computer mounted on the handlebar or stem. Heart rate data is transferred via a coded telemetry signal from the chest strap monitor. The data is then integrated to display current, average, and maximum biometric information. PREPARING FOR INSTALLATION The PowerTap hub comes either alone or in a pre-built wheel.
System Overview cont. COMPATABILITY The PowerTap hub is compatible with Shimano 8, 9, and 10 speed systems or Campagnolo 8, 9, and 10 speed systems. Freehub bodies may be interchanged. Reference FREEHUB REPLACEMENT for further instructions. The PowerTap is available in 130mm (Road) and 135mm (MTB) axle lengths. Only insert the correctly spaced PowerTap hub into your frame. For example, only use a 130mm-spaced hub in a 130mm road frame. Do not force the hub into any frame.
System Overview cont. SYSTEM INSTALLATION 1. Insert Wheel Into Frame Insert the PowerTap wheel into the frame. Make sure the axle is correctly positioned in the dropouts and secure the wheel in place with a skewer. 2. Attach Computer Shoe to Handlebar or Stem The shoe can be mounted on either the handlebar or stem. Secure the mounting base with cable ties. Slide the computer shoe in the direction of the arrow as depicted in either FIGURE 1A or 1B depending on mounting location.
