Make sure the brim of your helmet is just two fingers' width above your eyebrows. Then tighten the chin strap so you can fit only one or two fingers between it and your chin.
Beginners, position your handlebars at a height at which your back is bent no more than 45 degrees. "The lower you go, the more aerodynamic you may become, but also the greater the potential strain on your back," says Meaghen Harris, who rides for Liv/giant bicycles. (Tour de France contenders typically set their handlebars inches below seat level for that bent-over, streamlined effect.)
Set your seat height so that you have a 25-degree bend in your knee when your foot is at the bottom of a pedal stroke. This will maximize your pedal power, a study in the Journal of Strength and Conditioning Research found.

The second time get it up to half pressure, then let enough pressure out that you can push the tire away from the rim with your thumbs to be sure that the tube is not caught between the tire and the rim. If it is caught, repeat that step. When sure you are not going to have a pinch flat, inflate to full pressure.
