MORE INFORMATION
If you would like additional information about your bicycle, maintenance, or bicycling in general, there are
many resources in your community.
First, talk to your bicycle dealer. They have extensive experience with bicycles and riding in your community.
With this background, they can help you with your individual questions and help you find areas to enjoy
your new bicycle. In addition, most dealers stock a variety of book about cycling, including extensive
repair manuals.
The Presta valve has a narrower diameter and is only found on bicycle tires. To inflate a Presta valve tube using
a Presta headed bicycle pump, remove the valve cap; unscrew (counter-clockwise) 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 Schraeder 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 Schraeder 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.
WARNING
We highly recommend that you carry a spare inner tube when you ride your bike. 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.
