Presta Valve Tubes: Presta valves, also known as French valves or Sclaverand valves, are commonly used in high-performance bicycles, including road bikes and some mountain bikes. They are known for their narrow profile and require a specific pump head for inflation.
Schrader Valve Tubes: Schrader valves, also known as car valves or American valves, are often found in mountain bikes, hybrid bikes, and some children’s bicycles. They have a wider profile similar to car tire valves and can be inflated with standard air pumps.
Dunlop Valve Tubes: Dunlop valves, also known as Woods valves or Dutch valves, are less common but can still be found in some bicycles in Egypt. They have a similar design to Schrader valves but are thinner and use a different type of valve cap.
Tube Sizes:
The tube size required depends on the tire size of the bicycle. Here are some commonly found tube sizes in Egypt:
700c: This size is commonly used in road bikes, hybrid bikes, and some touring bikes. The corresponding tube sizes for 700c tires can range from 18-25c to 28-35c, depending on the tire width.
26-inch: This size is prevalent in mountain bikes and some urban and hybrid bikes. The corresponding tube sizes for 26-inch tires can range from 1.5 inches to 2.5 inches or more, depending on the tire width.
29-inch: This size, also known as 29ers, is popular in mountain bikes for improved rollover capability and enhanced traction.
The corresponding tube sizes for 29-inch tires can range from 1.9 inches to 3 inches or more, depending on the tire width.
20-inch
