1. Cerv lo bicycles will be set up by the dealer initially so that the right hand brake lever controls the rear brake and the left hand brake lever controls the front brake Make sure that your hands can reach and squeeze the brake levers comfortably If your hands are too small to operate the levers may be adjustable or you may need a different brake lever design Most brakes have some form of quick release mechanism to allow the brake pads to clear the tire when a wheel is removed or reinstalled When the brake quick release is in the open position the brakes are inoperative Ask your dealer to make sure that you understand the way the brake quick release works on your bike see figs 8 amp 9 and check each time to make sure both brakes work correctly before you get on the bike 2 How Brakes Work The braking action of a bicycle is a function of the friction between the brake surfaces usually the brake pads and the wheel rim To Cerv lo Owner s Manual 17 make sure that you have maximum friction available keep your wheel rims and brake pads clean and free of dirt lubricants waxes or polishes Brakes are designed to control your speed not just to stop the bike Maximum braking force for each wheel occurs at the point just before the wheel locks up stops rotating and starts to skid Once the tire skids you actually lose most of your stopping force and all directional control You need to practice slowing and stoppi
2. You the rider owner have control and knowledge of how often you use your bike how hard you use it and where you use it Because your dealer cannot track your use you must take responsibility for periodically bringing your bike to your dealer for inspection and service Your dealer will help you decide what frequency of inspection and service is appropriate for how and where you use your bike For your safety understanding and communication with your dealer we urge you to read this Appendix in its entirety The materials used to make your bike determine how and how frequently to inspect Ignoring this WARNING can lead to frame fork or other component failure which can result in serious injury or death A Understanding Metals Steel is the traditional material for building bicycle frames It has good characteristics but in high performance bicycles steel has been largely replaced by aluminum and some titanium The main factor driving this change is interest by cycling enthusiasts in lighter bicycles Properties of Metals Please understand that there is no simple statement that can be made that characterizes the use of different metals for bicycles What is true is how the metal chosen is applied is much more important than the material alone One must look at the way the bike is designed tested manufactured supported along with the characteristics of the metal rather than seeking a simplistic answer Metals vary widely in

C D Night Riding Riding a bicycle at night is many times more dangerous than riding during the day A bicyclist is very difficult for motorists and pedestrians to see Therefore children should never ride at dawn at dusk or at night Adults who chose to accept the greatly increased risk of riding at dawn at dusk or at night need to take extra care both riding and choosing specialized equipment which helps reduce that risk Consult your dealer about night riding safety equipment A WARNING Reflectors are not a substitute for required lights Riding at dawn at dusk at night or at other times of poor visibility without an adequate bicycle lighting system is dangerous and may result in serious injury or death Bicycle reflectors are designed to pick up and reflect car lights and street lights in a way that may help you to be seen and recognized as a moving bicyclist A CAUTION Check reflectors and their mounting brackets regularly to make sure that they are clean straight unbroken and securely mounted Have your dealer replace damaged reflectors and straighten or tighten any that are bent or loose A WARNING Do not remove the installed front or rear reflectors or reflector brackets from your bicycle They are an integral part of the bicycle s safety system Removing the reflectors may reduce your visibility to others using the roadway Being struck by other vehicles may result in serious injury or death If you choose to ri
