Keep your rides rolling smoothly with a pack of Positz Standard Inner Tubes. These inner tubes are designed for a wide range of 700c road bike tyres, accommodating widths from 28mm to 45mm, plus some 27″ old school bikes. This means they’ll fit most common road bike tyres, and even some wider gravel bike tyres. They feature a Schrader valve, also known as a car valve. This is the most common type of bicycle valve and is easy to inflate with a standard bike pump.

Having a spare inner tube is essential for any cyclist. Flats can happen at any time, and being prepared can save you the hassle of waiting for a taxi or walking your bike home. This pack of Positz Standard Inner Tubes includes two tubes, so you’ll have a replacement on hand whenever you need it.
