Pirelli SmarTUBE RS - 700x26-35c - Yellow

The SmarTUBE RS offers enhanced puncture protection due to its material. While durable, TPU tubes can be more sensitive to pinch flats if not properly inflated or installed. Always maintain recommended tire pressure.

Pirelli does not recommend using sealant with the SmarTUBE RS. It is designed to perform optimally on its own. Sealant is typically used with tubeless setups or specific compatible tubes.

The primary advantage of the Thermoplastic polyurethane (TPU) material is its low hysteresis, which translates to significantly lower rolling resistance and thus higher speeds, compared to traditional butyl or even standard TPU tubes.

Testing shows that the SmarTUBE RS achieves rolling speeds comparable to many sealant-based tubeless systems, offering a similar level of efficiency without the need for special rims, sealant, or complex setup.

This specific SmarTUBE RS model is designed for tire widths ranging from 700 x 26c up to 700 x 35c.

TPU tubes can often be repaired with specific TPU patches. Standard butyl patches are not compatible. Check the Pirelli website or specialized cycling shops for compatible repair kits.

The weight varies slightly by valve length: 32g for the 42mm valve, 33g for the 60mm valve, and 34g for the 80mm valve.

Ensure the valve stem is straight and properly seated in the rim hole. Check that the valve core is not loose (though it is non-removable, ensure it wasn't damaged during install).

Double-check tire for embedded objects (glass, thorns). Ensure tire pressure is adequate for riding conditions to prevent pinch flats. Verify no sharp edges exist inside the rim or on the rim tape.

Ensure the tube is only slightly inflated to help guide the bead. Work the tire bead into the rim channel. If using tire levers, be extremely careful not to pinch the tube.

Check for slow leaks around the valve stem or pinhole leaks. Re-inflate and listen for escaping air. A very slow leak might indicate a small puncture that needs repair or replacement.
