The tubes can withstand high PSIs (up to 120psi!) and remain airtight, removing the need for constant reinflation. More important than its thickness, each inner tube is evenly molded, ensuring that are no thin spots that will weaken the inner tube as it expands. Ride on bumpy or rocky trails in any type of weather. The inner tubes' weatherproof and evenly-molded butyl rubber compound can withstand both warm and cold weather without deteriorating or losing structural integrity. And there's no need to worry about storing these inner tubes for an extended amount of time. You can store these road bike tubes for years! Dependable 80mm Presta Valve Stems Presta valves offer both convenience and security. Specifically designed for high-performance tires and wheels, these valves are thinner and lighter. Its thin frame only requires a small hole in the road bike's rim, improving the rim's strength and performance. As a standard centered valve, the valve stem seats securely on the walls of the inner tubes, preventing leaks from the valve junction. Also, the valve's 80mm (3.14inches) length makes on-the-spot inflation a breeze, especially on deep-section rims. It is the longest length for Presta valves, specifically designed for deep-section rims that are taller than 55mm. The varying lengths of Presta valves ensure that there's enough length poking out (at least 1.5 inches) from the rim for ease in attaching a pump.
