Equipped with a 48 mm Presta (FV48) valve for precise inflation and a tight, reliable seal. Perfect fit for road, hybrid, gravel, and city bikes.
• STRONG AIR-TIGHT BUILD – Made from high-elasticity, mould-cured butyl rubber that seals air effectively and resists pressure loss. The Presta FV48 valve with reinforced rubber base ensures smooth, leak-free inflation. Thick walls maintain steady pressure, reduce refills, and provide a stable, safe ride.
• DURABLE & PUNCTURE-RESISTANT DESIGN – The thick butyl rubber body resists friction, heat, and road wear better than standard tubes. Built to handle long-distance rides and mixed terrain, it extends tube lifespan while reducing maintenance and replacement frequency.
• EXCELLENT SHOCK ABSORPTION – The flexible butyl rubber construction absorbs vibration and road impact for a smoother, more comfortable ride. The reinforced valve base adds durability and helps prevent leaks for consistent performance.
• COMPLETE 700C BIKE TUBE KIT – Compatible with road, hybrid, gravel, and city bikes. Each set includes two premium butyl rubber inner tubes and two tire levers for quick, easy installation. Fits 700x35C–43C tires perfectly for reliable everyday performance.
