Pirelli P Zero SmarTUBE RS TPU Inner Tube The Smartube RS TPU Inner Tube represents a significant leap in cycling technology, specifically engineered for riders who refuse to choose between convenience and high-end performance. By utilising a cutting-edge thermoplastic polyurethane formulation, this tube achieves rolling speeds that rival traditional sealant-based tubeless setups, yet it avoids the liquid mess and ongoing maintenance those systems require. It is remarkably light, starting at just 32g, and features a refined material structure that reduces energy loss through lower hysteresis. This means you get a more responsive ride and a 21% increase in speed over the previous generation, all while benefiting from enhanced puncture protection that keeps you moving through unpredictable road conditions. Designed to be the ultimate companion for your P ZERO Race RS tyres, the Smartube RS integrates seamlessly into both tube-type and tubeless-ready rims. Its compact volume makes it an ideal choice for those looking to shed rotating mass or carry a streamlined spare that does not compromise on durability. Every detail has been considered for the modern cyclist, from the sleek black valve stems available in lengths up to 80mm to the vibrant yellow finish. When you pair this tube with a performance tyre, you are not just buying an inner tube; you are investing in the fastest and most efficient system currently available, simplifying your maintenance routine without sacrificing a single watt of power.
