The key is to practice. When I got my driver's license, my father would not let me drive by myself until I had driven 1,000 miles with him AND had successfully completed changing each tire on the car.Originally Posted by Jen
The same should be required for everyone who rides a bike. Practice changing a tube until you are comfortable doing it. Winter is a great time to practice.
You do not take the chain off. The chain stays on the bike, but does come off of the cassette.
Check local bike shops for basic maintenance and repair classes. I have access to a bike repair stand and can give you a few lessons if you would like sometime. Just send me a PM.
