Key benefits One tube for both wheels: Straight valve design and included valve extender let this inner tube be used on either the front or rear wheel, reducing the need for multiple tube types. Easier inflation: The supplied valve extender improves access and makes inflating the tube quicker and more convenient. Built to last: At 1.9 mm wall thickness (compared with typical 0.9 mm tubes), this tube offers improved puncture resistance and longer service life. Reliable material performance: Made from quality butyl rubber for good thermal stability and air tightness; nontoxic and environmentally harmless. Features Compatibility: Straight valve design suitable for use on both FRONT and REAR wheels. Valve extender included: Helps reach valves on deeper rims and speeds up inflation with standard pumps and inflators. Durability: Extrathick 1.9 mm rubber provides stronger resistance to punctures and wear than standard tubes. Material: quality butyl rubber for consistent pressure retention and thermal stability. Safety/environment: Nontoxic material that is safe to handle and environmentally friendly. Practical applications Daily commuting: Keep a durable spare tube in your commuter bag to minimize downtime from flats. Long rides and touring: The thicker tube reduces the chance of punctures on longer routes, giving greater confidence on distance rides. Trail and light offroad use: Extra thickness and puncture resistance make this tube a reliable option for mixedsurface rides and rougher pavement. What this product solves Eliminates uncertainty about front vs. rear tube compatibility by using a straightvalve design usable in either position. Makes roadside or athome inflation easier via the included valve extender. Reduces frequency of replacements and flats thanks to a thicker, more punctureresistant construction. Maintains stable air pressure and performance through quality butyl rubber construction.
