Contrast 700 x 23c Road Bike Inner Tubes Presta Valve ETRTO 622-23 (Pair)

Product Information

And I doubt that the tire exploded due to over-inflation -- more likely the tire was not evenly mounted on the rim, and slipped off. The Dunlop valve, also known as a Woods is a variation of pneumatic valve that is rarely used on modern bikes. Designed for replacing the inner tube of your 700 diameter, 23 to 32 section tyres with a 48mm Presta valve. Schrader valves have a core that is sprung loaded, and the central pin can be depressed with a narrow object to release air from the tube. The tube needs to fit your tyre to avoid overstretching or pinching, both of which are likely to cause punctures and the tube material needs to be appropriate for your style of riding.

Suitable for, for example the tyre size 700x23C ETRTO size 19/25-700 and fitted with a 48 mm high Presta valve.

After that I was so careful not to over-inflate that I under-inflated the rear one and got pinch flats.

Changing an inner tube, as anyone who has been caught out by the side of the road will know, is a necessary evil.
