Tyre Valves

Types, Uses, and Maintenance Tyre valves may appear to be a small component of a bicycle, but they are essential for maintaining tyre pressure, ensuring compatibility with pumps, and enhancing overall riding performance. Understanding the types of valves and their uses can save both time and effort for young riders and their parents. Types of Tyre Valves Presta Valve:

• A slender, threaded valve commonly found on road bikes and high-performance mountain bikes.
• Features a locking nut at the tip that must be unscrewed before inflation.
• Ideal for rims with smaller valve holes (6.5 mm) and lightweight applications.
• Can be fragile; its thin structure may bend if handled roughly.

Schrader Valve:

• Similar to car and motorcycle valves, it is thicker and robust.
• Often found on entry-level and hybrid bikes.
• Requires a larger rim hole (8.5 mm) and is compatible with most air pumps, including those at petrol stations.

Dunlop Valve (Woods Valve):

• Rare but still used in some regions.
• Offers robust performance and is compatible with Presta-type pump tips.
• Requires a rim hole size similar to Schrader valves.

Regina Valve (Italian Valve):

• Exclusively used in older city bikes, primarily in Italy.
• Requires quick sealing post-inflation to avoid air loss, making it less user-friendly.
