About this item

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. | 100% SATISFACTION GUARANTEE - If you have any concerns, contact us through Amazon’s messaging centre and we’ll do whatever it takes to make sure your experience meets or exceeds expectations.
