In one sentence, describe what the following article is about: The International Organization for Standardization (ISO) measuring system uses millimeters to signify the size of your bicycle's wheel. If you don't have a measuring tape with metric rules, just be aware that there are 25.4 millimeters in one inch and determine the width with a calculator, multiplying inches x 25.4.  ISO sizing is considered the most reliable option for measuring your tires at home. It should give you the most accurate measurement.  Most tires are measured using both the standard and ISO method. Additionally, their sizes should be printed on the sidewall of the tire so you can easily check them. Measure in millimeters from the center of the wheel to only the inner edge of the tire. Once again, double the figure to determine the diameter. Most adult bicycle tires measured with the ISO system range from 650 to 700 millimeters in diameter. The ISO system includes both the bead seat diameter (BSD), as well as the width of the tire, in millimeters. As an example, a 700x35 c tire has a 622 millimeters BSD and is 35 millimeters wide, so its ISO designation would be 35-622. Similarly, a 26x2 inch tire would have a BSD of 559 mm and an ISO designation of 50-559. Use the same process listed above, across the tread from one side to the other. Keep in mind that tires of various widths can be used on the same bicycle wheel, as long as the difference is not too drastic. Remember when purchasing a new tire measured by the ISO system, the width is listed first, followed by the diameter. For example, a bicycle wheel sized 39 x 700 would have tread 39 millimeters wide and a wheel with a 700-millimeter diameter from the outer edge of one side of the tire to the other. Additionally, the BSD would be 622 mm.
Summary: Check if your bike's wheels are measured by the ISO system. Ensure the bike is propped up against the wall or on its kickstand. Measure the tire's width in millimeters. List the width first and the diameter second.

In one sentence, describe what the following article is about: Hair gel is ideal if you are going for a wet, spiked look. It will give your hair sheen and make it appear wet when it is in spikes. You can find hair gel at your local drugstore or online.  Hair gel is good for hair that tends to get dry and frizzy. Adding sheen to your dry hair can help it appear healthier and more styled. Hair gel may not be ideal if you have oily hair or hair that get oily during the hot weather months. You may decide to use a hair wax instead, as it will not make you hair look too greasy. Hair wax is good if you are trying to avoid the wet look and go for a more matte, spiked style. You can find hair wax at your local drugstore or online. This product is ideal for individuals with naturally oily or thick hair who do not want to end up looking greasy. Hair wax is also often used for individuals who have longer hair on the top of their head that they want to style. Pomade will give your hair shine and luster, as it is usually wax-based. It provides excellent hold and can be re-shaped throughout the day. Pomade can be found online as well as at your local drugstore. Use pomade on wet hair for less hold and more shine, and on dry hair for more hold and less shine. You can also use hair mousse if you are looking to add some volume and definition to your spiked hair look. If your hair lacks natural volume, you may get hair mousse to give your hair a little extra weight and texture. Hair mousse is also great for people with curly hair as it also helps to define your curls and prevents frizziness.
Summary:
Use hair gel for a wet look. Go for hair wax for a matte look. Apply pomade for a slick, styled look. Try hair mousse for more volume.
