Specifications

Size

1. Tube Dimensions:

   • 700 x 18c/23c/25c
     • Designed for 700c road wheels, a common standard for road, racing, and hybrid bikes.
     • Fits tire widths from 18mm to 25mm, making it ideal for lightweight and high-pressure road tires.

2. Applications:

   • Specifically suited for road bikes, touring bikes, and performance-oriented riding.

Valve Details

1. Valve Type:

   • Presta Valve
     • Narrower than Schrader valves, ideal for high-pressure road tires.
     • Features a lock nut for secure sealing during inflation.

2. Valve Length:

   • 48mm
     • Provides compatibility with a variety of rim profiles, including moderately deep-section rims.

3. Valve Core:

   • Non-Removable
     • Fixed valve core ensures reliability and simplifies use, although it limits compatibility with sealants.

4. Valve Stem:

   • Threaded
     • Threading allows for the use of a securing nut to prevent valve movement during inflation or riding.

5. Valve Angle:

   • 0 Degrees
     • Straight valve stem for optimal airflow and compatibility with Presta-specific pumps.

Material and Construction

1. Material:

   • Made from premium rubber, offering:
     • High elasticity for easy fitting across various tire sizes.
     • Excellent air retention, reducing the frequency of re-inflation.
     • Robust resistance to punctures, wear, and temperature variations.

2. Wall Thickness:

   • Standard thickness strikes a balance between durability and lightweight performance.

3. Seam Design:

   • Precision-engineered seams minimize the risk of splits or leaks under high pressure.

Design Features

1. Lightweight Construction:

   • Prioritizes minimal weight to enhance bike handling and performance for speed-focused riding.

2. Pressure Compatibility:

   • Designed to withstand high-pressure inflation, typically between 90-130 PSI, essential for road cycling.

3. Elasticity:

   • Provides flexibility to accommodate tire sizes within its range without sacrificing air retention.

4. Heat Resistance:

   • Built to endure heat generated during prolonged braking or high-speed descents.

Performance and Compatibility

1. Bike Types:

   • Compatible with road bikes, hybrid bikes, and lightweight touring bikes.

2. Rim Compatibility:

   • 48mm valve length fits standard and moderate-depth rims without requiring valve extenders.

3. Tire Compatibility:

   • Suitable for narrow-profile tires ranging from 18mm to 25mm in width.

4. Pump Compatibility:

   • Requires a Presta-compatible pump, often with a specific nozzle or adapter.

Color and Finish

1. Tube Color:

   • Black, the standard color for inner tubes, providing a clean and subtle appearance within the tire.

2. Valve Finish:

   • Nickel-plated valve stem for enhanced corrosion resistance and durability.
