Pirelli SmarTube P Zero EVO

The SmarTUBE family of tubes is made of TPU, a thermoplastic polyurethane characterised by high elasticity and mechanical resistance as well as extreme lightness. The SmarTUBE EVO has a TPU formula and offers performance in terms of flexibility, smoothness and comfort that can compete with latex hoses while guaranteeing up to 50% less weight compared to the latter. The SmarTUBE EVO also offers a 5% reduction in rolling resistance compared to the fast Pirelli SmarTUBE already on the market. This evolution of the famous Pirelli SmarTUBE incorporates feedback from the World Tour teams who work with the Milanese tyre manufacturer to help optimise the weight and speed of the P ZERO tyres, which will also benefit all loyal fans of the practical "clincher + tube" system. This version of the traditional yellow Pirelli SmarTUBE inner tube covers sizes from 25-622 to 28-622 and is available with three different black PRESTA valves: 42 mm, 60 mm and 80 mm for high-profile rims. Not compatible with rim brakes and cannot be repaired.
