2 PRO+ Bicycle Inner Tube 27 x 1-1/8 1.1/4 33mm Thorn Resistant PRESTA

• 27 x 1-1/8 to 1-1/4: This tube fits 27-inch wheels with tires that have a width range of 1-1/8 inches to 1-1/4 inches. It is typically used for road bikes and hybrid bicycles, often chosen by cyclists who prefer a thinner, more lightweight tire for speed and efficiency.

• The tube features a Presta valve, which is narrower and longer than the common Schrader valve, commonly used in higher-end road bikes and racing bikes. Presta valves are designed for use in modern rims with smaller valve holes and provide a more secure, leak-resistant fit.

Valve Length:

• 33mm: The 33mm length is ideal for most rim depths in 27-inch bicycles. This length provides enough reach for inflation while remaining compatible with standard hand or floor pumps.

Valve Core:

• Non-Removable Valve Core: The valve core is permanently sealed within the valve stem. While this means it cannot be removed for cleaning or replacement, it is designed to be robust, helping ensure air retention and preventing leaks.

Valve Stem:

• Threaded Stem: The threaded valve stem ensures a tight, secure seal when the valve nut is screwed onto the valve, preventing air loss during inflation and reducing the likelihood of valve damage over time.

Valve Angle:

• 0 Degrees: The valve stem is straight, offering ease of use and compatibility with most pumps. The straight design allows for quick and hassle-free inflation with any Presta-compatible pump.

Thorn-Resistant Rubber:

• The tube is made from thickened premium rubber, known for its excellent durability and air retention properties. The rubber is reinforced to provide extra protection against punctures from thorns, glass, or other sharp objects, ensuring a safer ride.

Durable Construction:

• The tube’s thicker construction is specifically designed to prevent flats caused by sharp debris while offering a good balance between weight, flexibility, and strength.

Presta Valve for High-Pressure Tires:

• The Presta valve is perfect for high-pressure tires, often found on road bikes. It helps maintain consistent air pressure, which improves ride quality and efficiency.

Threaded Valve for Secure Inflation:

• The threaded stem makes it easy to attach a pump or air compressor. Simply screw the pump head onto the valve for a secure connection.

High-Quality Rubber:

• The inner tube is made of rubber, known for its high resilience and excellent air retention.

Thicker Walls for Puncture Resistance:

• The tube’s rubber walls are designed to be thicker than standard tubes, providing an additional layer of defense against punctures.

Road Bikes:

• The 27 x 1-1/8 to 1-1/4 tube is primarily designed for road bikes, providing a lightweight option for faster riding.

Hybrid Bikes:

• Hybrid bikes can also benefit from this tube’s features, offering smooth performance on paved surfaces.

VINTAGE BIKES:

• Many older bicycles that use 27-inch wheels can also use this tube, making it an excellent choice for restoring classic bikes.

Thorn-Resistant Construction:

• The thicker rubber construction helps prevent punctures, making it ideal for cyclists who ride in areas with debris.

Durability for Extended Use:

• The rubber provides long-lasting protection, ensuring fewer flats and greater peace of mind.

High-Pressure Air Retention:

• Presta valves ensure consistent tire pressure for smooth rides.

Convenient Pumping:

• The threaded Presta valve stem allows for easy attachment to most pumps.
