Bicycle Repair Manual, 6th Edition

A clean, well-maintained bike will work efficiently and safely, and add to your enjoyment of cycling by giving you peace of mind. Safety and efficiency are closely linked. If your gears are not shifting correctly, for instance, they will not only affect your riding efficiency, but also tempt you to look down at them while riding to see what is causing the problem. As a result, you might take your eyes off what is happening on the road ahead and expose yourself to the possibility of a collision. The Bicycle Repair Manual will help you avoid such problems by demonstrating how to maintain your bike regularly and correctly.
