Inner tube

Introduction to the essential element of the city bike: the inner tube

For cyclists, the inner tube for city bike is an essential component that ensures the good performance and safety of the bike. It plays an important role in the comfort and efficiency of the ride, by allowing the tires to maintain the necessary air pressure for optimal grip and shock absorption. In this article, we will explore in detail the different aspects of this key element, from its definition to its installation, including par selecting the right model and methods of preventing punctures.

Definition and role of this key element in a city bike

The inner tube is a soft rubber covering that sits inside the tire. It is filled with air and allows the tire to maintain its shape and absorb road irregularities. In a city bike, it ensures a comfortable and safe ride by evenly distributing the rider's weight and providing good grip on urban surfaces. In addition, it plays a vital role in preventing punctures.

How to select the right size for your bike

Understanding Inner Tube Dimensions

To choose the right size inner tube, it is important to understand the dimensions indicated on the tire. These dimensions are usually presented as two separate numbers par an "x", par example 700x35C. The first number indicates the diameter of the tire in millimeters, while the second indicates its width.

Method to measure the size of this item

To measure the size of the inner tube, you can refer to the indications written on the sidewall of the tire. If these indications are not visible, use a tape measure to measure the diameter and width of the tire. Make sure to choose an inner tube whose dimensions match those of the tire to ensure proper installation and optimal performance.

The different models

The standard model

The standard inner tube model is made of butyl rubber and offers good puncture resistance and air holding. It is the most common choice for city bikes because of its balance between cost and performance.

The anti-puncture model

Puncture-proof inner tubes are reinforced with additional materials to provide increased protection against sharp objects and road debris. They are ideal for cyclists who ride on paved roads or rough trails where the risk of punctures is high.

The Presta or Schrader valve model

Inner tubes come with two types of valves: Presta and Schrader. The Presta valve is thinner and is often used on road bikes and high-end city bikes. The Schrader valve is wider and more robust and is commonly used on city bikes and mountain bikes. The choice between these two types of valves depends on the compatibility with your bike's rim.

Necessary tools

To install an inner tube on your city bike, you will need a few basic tools: tire levers, an air pump, a pressure gauge to check the pressure, and possibly a rim tape to protect the inner tube from the spoke nipples.

2. Remove the defective inner tube.
3. Check the inside of the tire for any sharp objects that could cause another puncture.
4. Insert the new inner tube starting par the valve.
5. Replace the tire on the rim, being careful not to pinch the inner tube.
6. Gradually inflate the inner tube to the recommended pressure.

Puncture Prevention and Maintenance
