Important Precautions:
• Before beginning any exercise program,consult your physician.
• Keep your eyesonthe 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 itscomponentsinwater or under high-
pressure sprays.
• Avoid spraying the unit directly with solvent mixture. Do not use thinner or other solventsto
cleanparts.
• If you are not familiar with bike maintenance please contact a professional bicycle mechanic
before servicing. The power measuring componentsof the PowerTap are highly complexand
should only be serviced by SarisCycling Group.
• The plasticbattery cover onthe hub should be removed only whenreplacing batteries.
Repeated disassembly may compromise the effectiveness of the O-ring seals. O-ringsshould be
inspected and replaced if necessary whenever the battery cover isremoved. Use a light
coating of grease whenreinstalling the battery cover onthe O-rings.
• During the course of repair do not remove the torque tube. There are no serviceable parts
inside. Special toolsare required for reassembly and calibration. If problemsare suspected
contact SarisCycling Group directly at 800-783-7257 (001 608 274 6550).

System Overview
THE POWERTAP SYSTEM
The PowerTap system includesa power-measuring hub which measurestorque and wheel
speed. Thisinformationistransmitted to a computer mounted onthe handlebar or stem. Heart
rate data istransferred via a coded telemetry signal from the chest strap monitor. The data is
thenintegrated to display current,average,and maximum biometricinformation.
PREPARING FORINSTALLATION
The PowerTap hub comeseither alone or ina pre-built wheel. If purchased alone,the hub must
be built into a complete wheel prior to use. Other itemsnecessary for installationand not provid-
ed include a cassette,spoke protector,reflectors, skewer,rim,tire,and tube (clincher rim) or glue
and tubular tire (tubular rim). See TABLE 1 to verify package contents.

COMPATABILITY
The PowerTap hub iscompatible with Shimano 8,9,and 10 speed systemsor Campagnolo 8,9,
and 10 speed systems. Freehub bodiesmay be interchanged. Reference FREEHUB REPLACEMENT
for further instructions.
ThePowerTap is availablein 130mm (Road) and 135mm (MTB) axlelengths. 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 SarisCycling Group to
address any special compatibility concerns.
WHEEL BUILDING
Contact a wheel building professional or dealer for assistance inbuilding the PowerTap wheel if
not purchased asa complete wheel. Due to the designof the hub,the load patternisnot the
same asa conventional hub. Slotting the hub flangesto accommodate bladed spokesisnot rec-
ommended and will void the warranty. Complete wheel building hub dimensions are listed in
TABLE 2.
Reference a spoke-length calculator to determine proper spoke length.
