Precautions:Important
• Before beginning any exercise program,consult your physician.
• Keep your eyes on the road.
DDoo nnoott
become overly engaged with the PowerTap display.
We recommend familiarizing yourself with computer functions while stationar y.
• The computer,receiver,and hub are water resistant,
nnoott
water 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 dir t 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 mix ture. 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 when
ever 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 nnoott
remove 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).

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.

TTHHEE PPOOWWEERR TTAAPP SSYYSSTTEEMM
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.
PPRREEPPAARRIINNGG FFOORR IINNSSTTAALLLLAATTIIOONN
The PowerTap SL2.4 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).See TABLE 1 to verify package contents.

The PowerTap SL2.4 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. 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 Saris Cycling Group to address any special
compatibility concerns.
WWHHEEEELL BBUUIILLDDIINNGG
Contact a wheel building professional or dealer for assistance in building the PowerTap SL2.4
wheel if not purchased as a complete wheel.

Due to the design of the hub,the load pattern is not the same as
a conventional hub.Slotting the hub flanges to accommodate bladed spokes is not recommended and will void the warranty. Complete wheel building hub dimensions are listed in TABLE 2 .

Position the heart rate monitor strap on your torso as pictured in FIGURE 6. The strap should rest just beneath the pectoralis muscles of
the chest. For best results slightly moisten the elec trodes where contact is made with skin. The hear t rate strap
mmuusstt
be worn to enable
the heart rate function. NOTE:The chest strap for the PowerTap SL2.4
uses a coded frequency and is not compatible with other manufacturer’s chest straps.
55.. VVeerriiffyy IInnssttaallllaattiioonn
Check to make sure all components are properly secured. Spin the
rear wheel and verify that in the upper left hand corner of the computer the transmission icon illuminates (FIGURE 7). This indicates
the hub is properly transmitting a signal to the receiver and computer. If the transmission icon is not illuminated consult Finding
Section Sensors for further instructions.
