Specifications

Size

1. Tube Dimensions:

   • 700 x 18c/23c/25c
     • Designed for 700c wheels, the standard diameter for road, hybrid, and performance bicycles.
     • Compatible with tire widths ranging from 18mm to 25mm, suitable for lightweight, high-pressure tires used in road cycling and racing.

2. Applications:

   • Optimized for road bikes, touring bikes, and lightweight hybrid bikes.

Valve Details

1. Valve Type:

   • Presta Valve
     • Narrow and tall, ideal for high-pressure systems used in road tires.
     • Lock nut at the tip secures the valve, ensuring airtight sealing.

2. Valve Length:

   • 52mm
     • Long enough for medium-profile and some deep-section rims, offering greater compatibility without requiring extenders.

3. Valve Core:

   • Non-Removable
     • Fixed core reduces the risk of accidental air loss or disassembly during inflation.

4. Valve Stem:

   • Threaded
     • The threaded body allows for a securing nut to hold the valve stem in place during inflation, reducing movement and enhancing stability.

5. Valve Angle:

   • 0 Degrees
     • Straight stem ensures easy compatibility with standard Presta pump heads.

Material and Construction

1. Material:

   • Premium Rubber:
     • Known for its excellent elasticity and airtight properties, offering reliable air retention.
     • Provides durability and resistance to punctures, wear, and extreme temperatures.

2. Wall Thickness:

   • Standard thickness ensures a balance between weight savings and durability, suitable for performance riding.

3. Seam Design:

   • Seamless construction minimizes the risk of weak points and air leaks, particularly under high-pressure conditions.

Design Features

1. Lightweight and Compact:

   • Minimal weight supports high-speed performance, aligning with the demands of road cyclists.

2. Pressure Compatibility:

   • Supports high-pressure inflation, typically ranging between 90-130 PSI, critical for road cycling.

3. Elasticity:

   • High elasticity ensures easy fitting within tires of varying widths in its specified range.

4. Heat Resistance:

   • Resists heat buildup caused by friction, particularly during prolonged braking or high-speed descents.

Performance and Compatibility

1. Bike Types:

   • Compatible with road bikes, racing bikes, and touring bikes.

2. Rim Compatibility:

   • The 52mm valve length is ideal for medium-depth rims and most road bikes, accommodating additional rim height without requiring extenders.

3. Tire Compatibility:

   • Fits tire widths from 18mm to 25mm, ensuring proper installation and functionality within this range.

4. Pump Compatibility:

   • Requires a pump with a Presta valve head or adapter for inflation.

Color and Finish

1. Tube Color:

   • Black, standard for inner tubes, ensuring a clean and concealed fit within the tire.

2. Valve Finish:

   • Nickel-plated stem enhances corrosion resistance and durability.
