INTRODUCTION & PRECAUTIONS

PRECAUTIONS: IMPORTANT

1. Before beginning any training program, always

check with your physician.

2. Keep your eyes on the road. Do not become over-

ly engaged with the Powertap display. We recom-

mend familiarizing yourself with computer

functions while stationary.

Thank you for purchasing the CycleOps Powertap

Powertap

Pro. Until now, instruments for measuring

power have been expensive, inaccurate, and difficult to
use. We designed the CycleOps Powertap

and

Powertap

Pro to be extremely accurate, reliable,

affordable, and easy to use and install. Power is the
ultimate performance yardstick for cyclists who want to
measure intensity. No other piece of cycling equipment
will give you a greater return on your investment.

6. The Powertap wheel does not include a quick

release skewer. CycleOps recommends using a

steel skewer.

7. Both sides of the Powertap hub should be built

with at least a two-cross spoke lacing pattern.

Because of the PowerTap design torque is trans-

ferred to the non-drive side as well as the drive

side.

8. Electromagnetic interference, such as interfer-

ence caused by high power lines, may briefly dis-

rupt the communication between the hub, chest

strap and computer.

9. The Powertap is available only in a 130 & 135mm

range of axle lengths to accommodate different

frames and uses. Only use similarly sized frames

and hubs.

Failure to adhere to these precautions may cause prema-

ture failure or incorrect operation of the unit and may void

the warranty.

3. The computer, receiver, and hub are water resistant.

However, avoid extended submersion or high-pressure

sprays directed at Powertap components.

4. Wash off dirt with a mild detergent on a soft cloth.

Wipe excess water off with a dry cloth. Do not apply

kerosene, paint thinner, alcohol, benzine or other such

solvents to any Powertap components.

5. The plastic cover on the hub should be removed only

when replacing batteries, or when allowing the unit to

dry after submersion in water. Only turn screws 7 times

maximum when reinstalling the battery cap. Hub

battery life is approximately 3 months of use.

Repeated disassembly may compromise the effective-

ness of the O-ring seals. O-rings should be inspected

and replaced if necessary whenever the battery cover

is removed. Be careful not to pinch the seals when

replacing the cover. Use a light coating of grease when

reinstalling the battery cap on the O-rings. See Pro

section for O-ring replacement.
