SmarTUBE Evo: Maximum speed, low rolling resistance, reduced weight and compact, for any kind of road riding or racing use.

The Pirelli SmarTUBE inner tube family is made of thermoplastic polyurethane TPU) that is a characterised by high elasticity and mechanical resistance, and extreme lightness. With an exceptionally low rolling resistance the SmarTUBE Evo offers increased acceleration, quicker climbing, and improved handling. The SmarTUBE EVO rolls 5% faster than the standard SmarTUBE. It is particularly well suited for road racing and fast road cycling where their enhanced speed characteristics are highly valued.

The SmarTUBE Evo tubes, in line with Pirelli’s TPU inner tube family, are extremely compact: 50% less space taken up in a jersey’s pocket or in a backpack, and up to 70% lighter compared to traditional butyl inner tubes, these TPU inner tubes make for an excellent space saving back up to carry on longer rides.  

What valve length do I need?
This will be dependent on the depth of the rim profile. Deeper rims will require a longer valve length. You need a valve that is long enough to pass through the rim and still have enough showing to attach a pump for inflation. Valves are available in 42mm, 60mm and 80mm lengths. It's generally recommended that the valve length is at least 15mm longer than the depth of your rim, for example if your rim is 45mm deep you will need an inner tube with a valve length of at least 60mm (45mm+15mm).
