The following are examples of the type of service you should perform
yourself. All other service, maintenance and repair should be per- formed 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 hard. Control cables and wheel spokes may stretch or “seat” when a new bike is first used and may require readjustment by your dealer. Your Mechanical Safety Check (Section 4.C) will help you identify some things that need readjustment. But even if everything seems fine to you, it’s best to take your bike back to the dealer for a checkup. Dealers typically suggest you bring the bike in for a 30 day checkup. Another way to judge when it’s time for the first checkup is to bring the bike in after three to five hours of hard off-road use, or
about 10 to 15 hours of on-road or more casual off-road use.
But if you think something is wrong with the bike, take it to your dealer before riding it again.
2.Before every ride: Mechanical Safety Check (see Section 4.C)
