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 inflate. To inflate
a Presta valve with a Schrader pump fitting, 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 fits
into the Schrader pump fitting. Close the valve after inflation. To let air out of a Presta valve,
open up the valve stem lock nut and depress the valve stem.

If you want to learn to do major service and repair work on your bike, you have three options:
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.
Regardless of which option you select, we recommend that you ask your dealer to check the
quality of your work the first time you work on something and before you ride the bike, just to
make sure that you did everything correctly. Since that will require the time of a mechanic, there
may be a modest charge for this service.
We also recommend that you ask your dealer for guidance on what spare parts, such as inner
tubes, light bulbs, etc. that would be appropriate for you to have once you have learned how to
replace such parts.
A. Service Intervals
Some service and maintenance can and should be performed by the owner, and require no special
tools or knowledge beyond what is presented in this manual.
The following are examples of the type of service you should perform yourself. All other service,
maintenance and repair should be performed in a properly equipped facility by a qualified bicycle
mechanic using the correct tools and procedures specified by the manufacturer.
1. Break-in Period:
Your bike will last longer and work better if you break it in before riding it
