SmarTUBE X: three times thicker than its previous version, giving it the maximum robustness and puncture resistance, for an urban, gravel or e-bike use

Milan (Italy), 13 September 2023 – Pirelli adds two new models to its range of premium inner tubes dedicated to road, gravel and e-bike tyres. The Pirelli SmarTUBE EVO and SmarTUBE X have just hit the market, respectively dedicated to the Pirelli P ZERO clinchers and the CINTURATO and ANGEL tyre families.

SMARTUBE EVO AND P ZERO: A COMBINATION OF SMOOTHNESS AND COMFORT

The SmarTUBE inner tubes family is made of TPU that is a thermoplastic polyurethane characterised by high elasticity and mechanical resistance, and extreme lightness. The new SmarTUBE EVO features a new TPU formula and offers a performance made of flexibility, smoothness, and comfort that can compete with latex inner tubes, while also guaranteeing up to 50% less weight compared to the latter. The new SmarTUBE EVO also allows an extra 5% less rolling resistance compared to the already fast Pirelli SmarTUBE on the market (*).

This evolution of the famous SmarTUBE models has responded to the feedback of the World Tour teams that work with Pirelli, to boost the performance centred on the P ZERO tyres’ lightness and speed, and extends these benefits to all those who love the convenience of the “clincher + inner tube” system.

Bright yellow as per “tradition”, available in a single version, which covers sizes ranging from 25-622 to 28-622, the new Pirelli SmarTUBE EVO comes with three different Presta valves, completely black: from 42 mm, 60 mm up to 80 mm for high-profile wheels. 

SMARTUBE X: ROBUSTNESS AND HIGH PUNTURE RESISTANCE

Pirelli SmarTUBE X, on the other hand, is the new TPU inner tube dedicated by Pirelli to the tyres of the CINTURATO and ANGEL families: three times thicker than the current CINTURATO SmarTUBE (which it is replacing), the SmarTUBE X offers robustness and puncture resistance. It is particularly suitable in city settings or for fast commuting.

SmarTUBE X comes in two separate lines: CINTURATO SmarTUBE X for tyres from 28-622 to 40-622 and from 40-622 to 50-622, with Presta or Schrader valves, and ANGEL SmarTUBE X for tyres from 28-622 to 42-622 and from 42-622 to 62-622, with Presta or Schrader valve options.

The new SmarTUBE EVO and SmarTUBE X, in line with Pirelli’s TPU inner tube family, are extremely compact: -50% space taken up in the jersey’s pockets or in the backpack compared to the traditional butyl inner tubes, while preserving - like the latter type - the necessary airtightness.

The first sizes are already available on the market, the range is expected to be complete by the end of September 2023.

(*) In-house testing by Pirelli with P ZERO Race tyres sized 28-622; Angel GT Urban sized 28-622, 42-622, 47-622, 52-622 and Angel DT Urban sized 28-622 and 42-622.
