700x25c inner tube - Wide Road (23-28c) Presta 42mm Valve (also 27/28")

  • This size of inner tube is used on road, sportive, gran fondo, winter training and touring bikes.
  • This is also the same size at the standard tube fitted Specialized road bikes when new.
  • Slightly larger profile for the new trend of wider road tyres
  • Weighs 130g - extra material for better protection in wider tyres
  • Presta valve type (AKA High Pressure Valve or French Valve).
  • 42mm length valve suitable for most standard depth rims up to 30mm.
  • Threaded valve stem with security ring prevents rattling on the rim and makes pump attachment easier.
  • Reinforced dual thickness tube/valve interface to prevent punctures.
  • Butyl rubber construction

These innertubes are compatible with the following ETRTO tire sizes:

Metric Sizes

700 x 23 = ETRTO 23-622
700 x 24 = ETRTO 24-622
700 x 25 = ETRTO 25-622
700 x 28 = ETRTO 28-622

Imperial Sizes

28 x 1" = ETRTO 25-622
28 x 1 1/8" = ETRTO 28-622

27 x 7/8" = ETRTO 22-630
27 x 1" = ETRTO 25-630
27 x 1 1/8" = ETRTO 28-630

As you can see this tube will fit both the ETRTO rim sizes 622mm and 630mm. You may know that rim and tyre sizes must match each other exactly, but due to the flexibility of an inner tube they can often fit more than one rim size.
