Specifications

Size

1. Tube Dimensions:

   • 700 x 18c/23c/25c
     • Designed for 700c wheels, the standard diameter for road and performance bicycles.
     • Compatible with tire widths ranging from 18mm to 25mm, making it ideal for lightweight, high-pressure road bike tires.

2. Applications:

   • Specifically suited for road bikes, time trial bikes, and lightweight hybrid bikes.

Valve Details

1. Valve Type:

   • Presta Valve
     • Slim and lightweight, engineered for high-pressure systems and commonly used on performance bicycles.
     • Equipped with a lock nut for secure inflation and an airtight seal.

2. Valve Length:

   • 60mm
     • Optimized for medium to deep-section rims, providing sufficient length for easy access without needing an extender for most wheels.

3. Valve Core:

   • Non-Removable
     • The fixed valve core minimizes the risk of unintentional air leaks during inflation or maintenance.

4. Valve Stem:

   • Threaded
     • The threading along the stem allows a locking nut to secure the valve, stabilizing it during inflation and preventing movement.

5. Valve Angle:

   • 0 Degrees
     • Straight valve design for seamless compatibility with standard Presta pump heads.
