Durability you can feel

Built from latex-free premium butyl rubber, these tubes feature 45% more rubber content and offer 4.8x greater flexibility with thicker sidewalls. The thicker construction helps resist daily wear and accommodate variable terrains, giving you steadier air retention and dependable performance ride after ride.

• Latex-free for versatile handling
• Thicker sidewalls to improve resilience

Soft, controlled ride and safety

Even on uneven pavement, the tube acts as a cushion at the point of contact. The 4x thicker butyl rubber contributes to shock absorption for a smoother feel on rough surfaces, while an explosion-proof design helps seal quickly after a puncture to maintain pressure and reduce risk. The latex-free material also simplifies handling.

Note: Regular inspection of tires and rims is advised for ongoing safety and performance. This kit aims to support stability across seasons and weather conditions.
