700c is the standard size for tyres and tubes for most road bikes, racing bikes, fixie and commuter style bicycles too. Some common size 700c tubes are as follows:
For road bikes: 700c x 23mm, 700c x 25mm and 700c x 28mm.
For gravel and bike paths: 700c x 32mm and 700c x 35mm.
You may notice that tubes are flexible enough to suit more than one tyre size. For example, if you need tubes to fit your 700 x 23 tyre, then select a tube that would cover that size and more – something like the Positz Road Bike Inner Tubes 700 x 18-25 would be a perfect match.
