The League of American Bicyclists offers road-skills classes throughout the United States to make bicyclists aware of the hazards they face sharing the roadways The classes teach you how to avoid collisions with automobiles and dodge road hazards You can find a class near you at wwwbikeleague org/programs/education Contact the League of American Bicyclists at 1612 K St NW, Suite 800, Washington, DC 20006-2850 (phone: 202-822-1333; e-mail: bikeleague@bikeleagueorg; Web: wwwbikeleagueorg)

If you re going to be spending any amount of time on your bike, you should try to make it as comfortable an experience as possible You can do a number of things to improve the riding experience, and one of these things is to adjust the handlebars For road bikes, the old-school approach to positioning the handlebars was to have the handlebar ends run parallel to the top tube in the frame Although being bent over like the Hunchback of Notre Dame may be good for aerodynamics, having your weight supported on outstretched arms is not very comfortable for everyday riding To position your handlebars for a more enjoyable ride, set them such that they leave your back at a 45-degree angle (see Figure 18-1) You may need to rotate the handlebars within the clamp that holds them or change or adjust the stem as described in 15 With the proper adjustment, you can ensure that the weight of your upper body will be distributed between your torso and your arms

Another consideration for the handlebars is the position of the brake levers You want to be able to squeeze the levers while your hands are resting comfortably on the handlebar If you have to reach or curl your wrists to use the brakes, they aren t positioned properly

Just as important as adjusting the handlebars is finding the right position for your saddle If your saddle is set too high or too low, you ll lose efficiency as you pedal and may even cause strain or injury to your body We can t tell you how often we see people riding with an improperly positioned saddle in many cases, a saddle set too low with the person s legs in a bow-legged position, which causes strain on the knees You know that your saddle is set to the right height if you can just barely place your toes and the balls of your feet on the ground when you sit on the saddle (see Figure 18-2) Go for the maximum leg extension without locking out your knees or bobbing your hips in order to reach low Pain in the back of the kneecaps results from seats too low; pain in the front, from seats too high Your leg should be bent at a slight angle when your foot is on the pedal at its lowest position

Another adjustment you can make is the fore and aft (how far back or forward the seat is positioned) If your seat is too far to the rear, you ll be stretching to reach the bars, which puts strain on your back and knees (See 9 for how to adjust fore and aft)

Before you set off for a ride, make sure you check your tire pressure If your tires aren t properly inflated, riding will be less efficient and you ll be at greater risk of damaging your rims and getting flats When checking tire pressure, it isn t enough to pinch the tires to feel whether they re firm tires that are under-inflated feel very similar to those with the proper amount of pressure The most accurate and surefire way of checking tire pressure is to use a tire-pressure gauge When filling tires with air, pump them to the recommended pressure listed on the sidewall of the tire
