the valve stems on your bicycle.
The Schraeder valve (g. 18a) is like the valve on a car tire. To inate a
Schraeder valve tire, remove the valve cap and clamp the pump tting onto the
end of the valve stem. To let air out of a Schraeder valve, depress the pin in the
end of the valve stem with the end of a key or other appropriate object.
The Presta valve (g. 18b) has a narrower diameter and is only found on
bicycle tires. To inate a Presta valve tire using a Presta headed bicycle pump,
remove the valve cap; unscrew (counterclockwise) the valve stem lock nut; and
push down on the valve stem to free it up. Then push the pump head on to the
valve head, and inate. To inate a Presta valve with a Schraeder pump tting,
you’ll need a Presta adapter (available at your bike shop) which screws on to the
valve stem once you’ve freed up the valve. The adapter ts into the Schraeder
pump tting. Close the valve after ination. To let air out of a Presta valve, open
up the valve stem lock nut and depress the valve stem.

Patching a tube is an emergency repair. If you do not apply the patch
correctly or apply several patches, the tube can fail, resulting in possible
tube failure, which could cause you to loose control and fall. Replace a
patched tube as soon as possible.
5. Service
WARNING: Technological advances have made bicycles and bicycle
components more complex, and the pace of innovation is increasing.
It is impossible for this manual to provide all the information required
to properly repair and/or maintain your bicycle. In order to help minimize
the chances of an accident and possible injury, it is critical that you have
anyrepairormaintenancewhichisnotspecicallydescribedinthis
manual performed by your dealer. Equally important is that your individual
maintenance requirements will be determined by everything from your
riding style to geographic location. Consult your dealer for help in
determining your maintenance requirements.
WARNING: Many bicycle service and repair tasks require special
knowledge and tools. Do not begin any adjustments or service on
your bicycle until you have learned from your dealer how to properly
complete them. Improper adjustment or service may result in damage to
the bicycle or in an accident which can cause serious injury or death.
If you want to learn to do major service and repair work on your bike:
1. Ask your dealer for copies of the manufacturer’s installation and service
instructions for the components on your bike, or contact the component
manufacturer.
2. Ask your dealer to recommend a book on bicycle repair.
3. Ask your dealer about the availability of bicycle repair courses in your area.
