How to measure men's body size:

Chest measurement:
Keep the body perpendicular to the ground and use a tape measure to measure the widest circumference of your chest. The tape is not rolled and should be parallel to the ground during the measurement. Keep the neck relaxed and maintain natural breathing. The tape measure should slighly press against the area of measurement

Bike tyres:

To choose the right size, first pay attention to the size shown on the tyre. The standard tyre size for mountain bikes is 26 inches. Example: 26 × 200 is usually used for mountain bike tyres. The first number indicates the tyre diameter and the second is its width. When you change to another tire, you must keep the same diameter and the width can be changed according to personal preference. A narrower tyre can make the car faster, and a wider one can make the ride more comfortable. In addition, you must also confirm that the selected tyre matches the inner tube. Check if the size marked on the tyre matches the size written on the inner tube. If the inner tube size is 26 × 1.75/2.1, this means that you can use a tyre with a diameter of 26 and a width between 1.75 and 2.1. Example: A tube with a size of 26 × 1.75/2.1 is matched with a 26 × 2.00 tyre.

The first step is to check which types of nozzle you need:
· Law mouth: commonly used in road cycling. Some models have a perfect match with the valve tip and specific wheels
· American air nozzle: In most cases, it is only suitable for mountain bikes (similar to the air nozzle of car tyres)

Second, choose a tube size that is compatible with your tires:
· The standard diameter of road bikes is 28 inches (700)
· Some smaller tires may also be 26 inches (650)
· Use dimensions marked on existing or replacement tires, the first number is the diameter and the second number is the width.
· When you change the inner tube, you must use the same size: a tube with a size of 700 × 18/25, which is compatible with tires with a diameter of 700 and a width of 18 to 25. Example: A tube with a size of 700 × 18/25 is suitable for tires measuring 700 × 23
