Schwalbe 700x18-25c Presta 42mm Valve (also 27/28")
- This size of inner tube is used on road, triathlon and some slim tyres for commuting/touring bikes.
- Presta valve type (AKA High Pressure Valve or French Valve).
- Removable and replaceable valve core.
- 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.
- Light weight butyl rubber construction.
These innertubes are compatible with the following ETRTO tire sizes:
700 x 18 = ETRTO 18-622
700 x 21 = ETRTO 21-622
700 x 23 = ETRTO 23-622
700 x 25 = ETRTO 25-622
28 x 3/4" = ETRTO 19-622
28 x 7/8" = ETRTO 22-622
28 x 1" = ETRTO 25-622
27 x 7/8" = ETRTO 22-630
27 x 1" = ETRTO 25-630
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.
