Page 5: Precautions: Important
Precautions: Important • 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, receiver, and hub are water resistant, not water proof. - Page 6 Precautions: Important, cont. • The PowerTap wheel does not include a quick release skewer. CycleOps recommends using a steel skewer. • Both sides of the PowerTap should be built using a 3x spoke lacing pattern. Because of the design of the PowerTap, torque is transmitted through the hub to the non-drive side. For additional questions please consult WHEEL BUILDING.

Page 7: System Overview
PREPARING FOR INSTALLATION The PowerTap SL hub comes either alone or in a pre-built wheel. If purchased alone, the hub must be built into a complete wheel prior to use. Other items necessary for installation and not provided include a cassette, spoke protector, reflectors, skewer, rim strip, tire, and tube (clincher rim) or glue and tubular tire (tubular rim). -
Page 8: Compatibility
System Overview cont. COMPATABILITY The PowerTap SL 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 and 135mm axle lengths. Only insert the correctly spaced PowerTap hub into your frame. -
Page 9: System Installation
FIGURE 1 SYSTEM INSTALLATION 1. Insert Wheel Into Frame Insert the PowerTap SL wheel into the frame. Make sure the axel is correctly positioned in the dropouts and secure the wheel in place with a steel skewer. 2. Attach Receiver to Seat Stay Attach the Shark Fin receiver a maximum of 3 inches from the PowerTap hub using cable ties. - Page 10 For best results slightly moisten the electrodes where contact is made with skin. The heart rate strap must be worn to enable the heart rate function. NOTE: The chest strap for the PowerTap SL uses a non-coded frequency and is not compatible with other manufacturer’s chest straps.
- Page 11 7. Verify Installation Check to make sure all components are properly secured. Spin FIGURE 7 the rear wheel and verify that in the upper left hand corner of the computer the transmission icon illuminates (FIGURE 7). This indi- cates the hub is properly transmitting a signal to the receiver and computer.
