Tubes Pirelli P ZERO™ SmarTUBE EVO 25/28-622, Presta 42mm The P ZERO™ SmarTUBE EVO is Pirelli's latest innovation in the world of tubes, aiming to improve performance in modern cycling. They are the result of our development for World Tour tires, now available for everyday riding. They are made from thermoplastic polyurethane (TPU), which can save up to 70% of the weight of conventional butyl inner tubes and almost 50% of the pocket space, while being stronger than butyl as a raw material. The P ZERO™ SmarTUBE EVO rolls 5% faster than a standard SmarTUBE, making the bike accelerate and climb hills faster while improving handling. The P ZERO™ SmarTUBE EVO comes with a Presta valve that is available in a range of heights to fit any rim. Use: road bikes, time trial bikes, marginal endurance bikes (intended for use on all types of road riding where low rolling resistance is a priority - ideally in combination with Pirelli P ZERO tires) Material: TPU (thermoplastic polyurethane) Further development of Pirelli TPU, now with even lower hysteresis for lower rolling resistance, at the same weight and compact volume. Galusco valve: RVC mechanism with glued inside, length 42 mm, black color for a clean and neat look.Dimension: 700x25/28cValve length: 42mmWeight: 35gCompatibility: disc brakes only
