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 rst 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.
