Valve Details

1. Valve Type:

   • Presta Valve
     • Slim, lightweight valve suited for high-pressure tires and performance-oriented wheels.
     • Equipped with a locking nut for a secure seal, preventing air leaks.

2. Valve Length:

   • 60mm
     • Designed for mid to deep-profile rims, eliminating the need for valve extenders on rims up to ~40mm deep.
     • Provides ample clearance for most Presta-compatible pump heads.

3. Valve Core:

   • Non-Removable
     • Increases durability and reduces potential maintenance issues.
     • Eliminates the risk of accidental unscrewing during inflation.

4. Valve Stem:

   • Threaded
     • Threads enable the use of a locking ring to secure the valve to the rim, preventing movement during inflation or riding.

5. Valve Angle:

   • 0 Degrees (Straight)
     • Ensures straightforward alignment with pump heads for ease of inflation.

Material and Construction

1. Material:

   • Premium Rubber
     • Provides exceptional air retention, flexibility, and durability.
     • Resistant to UV light, ozone, and temperature variations, ensuring reliability in diverse conditions.

2. Wall Thickness:

   • Standard Thickness
     • Balances puncture resistance with a lightweight design for optimized performance.

3. Construction:

   • Seamless Design
     • Eliminates weak points, minimizing the risk of air leaks or blowouts.
     • Precision-molded for a uniform shape and superior fit within the tire.

Performance Features

1. Tire Compatibility:

   • Compatible with tires in the 28c to 35c range, allowing flexibility across various bike types.
   • Suited for different inflation pressures based on tire width:
     • 28c: 85–100 PSI for road efficiency.
     • 32c: 60–80 PSI for urban and mixed terrain.
     • 35c: 50–65 PSI for enhanced comfort and stability.

2. Elasticity:

   • High elasticity ensures a snug fit, reducing risks of pinch flats and allowing for easy installation.

3. Puncture Resistance:

   • Durable rubber material resists punctures and abrasions, extending tube longevity.

4. Air Retention:

   • The rubber and a secure Presta valve system provide excellent air retention, requiring less frequent top-ups.

Design Features

1. Valve Design:
