Specifications

Size

1. Tube Size:

   • 650 x 18c/23c/26c
     • Compatible with 650c wheels, a common size for road and triathlon bikes.
     • Designed to fit tire widths ranging from 18mm to 26mm, ensuring versatility for narrow, high-performance road tires.

2. Applications:

   • Ideal for lightweight road, racing, and time trial bikes where rolling resistance and aerodynamics are prioritized.

Valve Details

1. Valve Type:

   • Presta Valve
     • Thin and lightweight, designed for high-pressure road tires.
     • Commonly used on road, triathlon, and performance bikes.

2. Valve Length:

   • 60mm
     • Long valve length is suitable for deep-section rims, typically ranging from 40-60mm in depth.
     • Ensures sufficient clearance for air pumps, eliminating the need for valve extenders on deep rims.

3. Valve Core:

   • Non-Removable
     • Fixed core minimizes the risk of accidental detachment during inflation or riding.
     • Enhances reliability for consistent air retention.

4. Valve Stem:

   • Threaded
     • Provides better grip for the pump head, reducing the chance of air leaks during inflation.
     • Compatible with threaded Presta valve caps for added protection against dirt and debris.

5. Valve Angle:

   • 0 Degrees
     • Straight valve stem for compatibility with most pumps and inflators.

Material and Construction

1. Material:

   • Made from high-quality rubber, ensuring:
     • Superior elasticity and durability.
     • Excellent air retention, reducing the frequency of inflations.
     • Enhanced resistance to punctures and tears under high-pressure conditions.

2. Wall Thickness:

   • Standard thickness provides a balance between weight, durability, and performance.

3. Seam Construction:

   • Heat-sealed seams ensure durability and reduce the risk of splits or leaks.

Design Features

1. Lightweight Design:

   • Specifically engineered for performance bikes where weight is a critical factor.

2. Flexibility:

   • Designed to accommodate a range of tire widths, making it a versatile choice for various road bike setups.

3. Heat Resistance:

   • Butyl rubber construction can withstand the high temperatures generated by prolonged braking on road bike rims.

4. Optimized for High Pressure:

   • Suitable for inflation pressures required by road tires, typically ranging between 90-130 PSI (consult your tire specifications for exact values).

Performance and Compatibility

1. Bike Types:

   • Designed for road bikes, time trial bikes, and triathlon bikes.
   • Commonly used for performance-focused riding, including racing and training.

2. Rim Compatibility:

   • Compatible with 650c rims, including deep-section rims up to 60mm in depth.

3. Pump Compatibility:

   • Compatible with Presta-specific pump heads or dual-valve pumps.

4. Tire Compatibility:

   • Works with tire sizes ranging from 18mm to 26mm in width.

Color and Finish

1. Tube Color:

   • Standard black, providing a clean and unobtrusive look inside the tire.

2. Valve Finish:

   • Nickel-plated valve stem for enhanced corrosion resistance and a polished appearance.
