If (like us) your favourite inner tubes (when we are not running tubeless) are those made by Schwalbe
- We use the AV4 for Brompton 16 inch models - that is the A Line, C Line
- We use the SV7 for Brompton 20 inch models - the G Line
This is how the new SV7 box / inner tube now looks

You may notice next time you get one that the packaging has changed slightly (and also the logo writing on the inner tube itself)
This is a rolling change that will take place over time
