The PowerTap system includes a power-measuring hub which measures torque and wheel
speed. This information is then transmitted via digital radio frequency to a receiver mounted on
the seat stay. The data is wired to the PowerTap computer mounted on the handlebar. The com-
puter receives the signal from the heart rate monitor chest strap to provide heart rate information.
All of this information is then processed for display on the computer.
PPrreeppaarriinnggffoorrIInnssttaallllaattiioonn
The PowerTap hub comes either in a pre-built wheel or alone, ready to build into a wheel. The
power measuring hub must be built into a complete wheel prior to installation. Other items nec-
essary for installation are a cassette, spoke protector, reflectors, skewer, rim strip, tire, and tube
(clincher rim) or glue and tubular tire (tubular rim). Please read all instructions prior to installation.
Also take a moment to verify the package contents. The installation procedure with a complete
wheel requires only a trimmer to clip the cable ties. However, assembling the wheel, cassette and
other parts requires the proper tools and experience. If you are unsure of any step of the proce-
dure or do not have all of the tools necessary for installation, contact your local dealer
for assistance.

The PowerTap SL hub is compatible with Shimano 8, 9, and 10 speed systems or
Campagnolo 8, 9, and 10 speed. Free hub bodies may be interchanged. See page 24 for
instructions.
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. Doing so may cause failure of the frame, hub, or both, and will void the
warranty. Contact your dealer or PowerTap to address any special compatibility issues.
WWHHEEEELLBBUUIILLDDIINNGG
Contact your local wheel building professional or dealer for assistance in building the PowerTap
hub if not provided as a complete wheel. The flanges are drilled for 14 or 15 gauge spokes. Use
at least a two-cross pattern on both sides of the hub. Due to the design of the hub, the load path
is not the same as with a conventional hub. Slotting the hub flanges to accommodate bladed
spokes is not recommended and will void the warranty.

Thestrap shouldrestjustbeneath thepectoral musclesof the chest.Make
sure the electrodes on the strap are slightly moist where it contacts the
skin for best results. The heart rate strap must be worn to enable the heart
rate functionality of the PowerTap.

Check all the components to make sure they are securely attached.
Spin the rear wheel and verify that the transmission icon on the computer
display is illuminated. This indicates that the hub is sending a valid signal
through the receiver to the cpu. (see figure 6). Adjust the receiver
if necessary.
