Precautions:Important• Before beginning any exercise program,consult your physician.• Keep your eyes on the road.DDoo nnoottbecome overly engaged with the PowerTap display.We recommend familiarizing yourself with computer functions while stationary.• The computer,receiver,and hub are water resistant,nnoottwater proof. Avoid sustained water contact and do not deliberately place the PowerTap or its components in water or under high-pressure sprays. Therefore caution should be used when riding in rain. Following such rides,special precautions should be taken including removing the PowerTap plastic twist cap and allowing the hub to air dry.• Wash off dirt with a cloth soaked in a weak mixture of neutral detergent and water and wipe excess water off with a dry cloth Avoid spraying the unit directly with solvent mixture. Do not use thinner or other solvents to clean parts as they may dissolve the plastic console casings.• If you are not familiar with bike maintenance please contact a professional bicycle mechanic before servicing. The power measuring components of the PowerTap are highly complex and should only be serviced by Saris Cycling Group.• The plastic cover on the hub should be removed only when replacing batteries or when allowing the unit to dry after submersion in water.Repeated disassembly may compromise the effectiveness of the O-ring seals.O-rings should be inspected and replaced if necessary whenever the battery cover is removed. Use a light coating of grease when reinstalling the battery cap on the O-rings.• During the course of repair ddoo nnoottremove the torque tube. There are no serviceable parts inside. Special tools are required for reassembly and calibration. If problems are suspected contact Saris Cycling Group directly at 800-783-7257 (001 608 274 6550).5
Precautions:Important,cont.• The PowerTap wheel does not include a quick release skewer.CycleOps recommends using a steel skewer.• BBootthh ssiiddeess ooff tthhee PPoowweerrTTaapp sshhoouulldd bbee bbuuiilltt uussiinngg aa 33xx ssppookkee llaacciinngg ppaatttteerrnn.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.• 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.6
System OverviewTTHHEE PPOOWWEERR TTAAPP SSYYSSTTEEMMThe PowerTap system includes a power-measuring hub which measures torque and wheelspeed.This information is transmitted to a computer mounted on the handlebar or stem.Heartrate data is transferred via A coded telemetry signal from the chest strap monitor. The data isthen integrated to display current,average,and maximum biometric information.PPRREEPPAARRIINNGG FFOORR IINNSSTTAALLLLAATTIIOONN The PowerTap SL2.4 hub comes either alone or in a pre-built wheel.If purchased alone,the hubmust be built into a complete wheel prior to use.Other items necessary for installation and notprovided include a cassette,spoke protector,reflectors,skewer,rim strip,tire,and tube (clincherrim) or glue and tubular tire (tubular rim).See TABLE 1 to verify package contents.TABLE 1 71 PowerTap hub (or built wheel)1 PowerTap computer1 Chest strap4 Foam mounting tapes12 Cable ties1 Training With Power guide1 PowerTuned Agent CD1 Link USB Cable1 Extra CPU BatteryQty ItemPPaacckkaaggee CCoonntteennttss

CCOOMMPPUUTTEERR SSEETTUUPP 55This setup allows the CPU to learn a new device or sensor such as the hub,heart rate strap andoptional cadence sensor. NOTE:This process only needs to be used if a new sensor or hub isbeing used in conjunction with your CPU or vice versa and if batteries are changed in the hub orchest strap. There are 2 Learn sequences,1 and 2. Learn 1 is used when you have switched sen-sors or the CPU and there are no other like bikes with PowerTap SL2.4 within a 30’radius. Learn 2is used if there are other devices in the area but requires you to remove and reinsert the batterybefore activating the Learn 2 sequence.1) To manually change the hub I.D.Push [Select] to toggle through the Hub I.D.Press [Mode] to save.2) In most cases the Hub I.D.will not be known so you can "learn" the I.D.bypressing [Mode] to advance through the Hub I.D.settings to Learn 1. NOTE:Learn 1 will search for any active hub so be sure that there are no other active hubs in the area. If there are,proceed to Learn 2.3) Learn 1 is initiated by Holding [Select] until "Learn" begins flashing.When the CPU has learned the device I.D.it will display the I.D.Press [Mode] to advance to the next device I.D. If it did not learn the deviceit will take you back to the most recent Hub I.D. NOTE:Make sure the hub is"awake" by spinning the wheel or axle.4) Press [Mode] until Learn 2 is displayed. Learn 2 is used when there are other "awake" or active PowerTap SL 2.4 hubs within a 30 foot radius.5) Initiate Learn 2 by first removing the batteries from the hub for 5 seconds and replacing them.Then hold [Select] until "Learn" begins to flash. When the CPU has learned the hub I.D.it will display the I.D.Press [Mode] to save and proceed to the next device I.D.If it did not learn the device it will take you back to the most recent Hub I.D. 30hubId45847hubIdLEArn1hubIdLEArn1flashinghubIdLEArn2hubIdLEArn2flashing
